search modeling machine components

[Ste_d]

Good morning to all students and not!

Finally in our university they decided to put a course of "advanced 3d modeling" (optional examination that I choose to do very gladly) i.e. an advanced course of use of solidworks to realize a bit more complicated components of an ahahahah tree!
the exam previews the carrying out of a work to groups so we have to choose a component of machine made from 7-8 pieces and model it. as an example the prof showed us in class a brake to the jaws that he had found on a book of constructions of machines. Do you have any ideas or ideas to give us? do you know how to tell us where to go to see or what texts to consult to find something? of course the various proposals we bring them to show them and then he will decide which to assign us!

Thank you in advance!

Hi.
you could take a look at the thread of the reducer or oil pump.
http://www.cad3d.it/forum1/showthread.php?t=25085
http://www.cad3d.it/forum1/showthread.php?t=22834simpler components of these are not found....then you could model a change (other topic of the forum) but would become too complex compared to the 7-8 components.

or a clutch (repairing the tables would be very difficult).

is a question that has already been submitted on the forum, I think everything you like and interest: a carburetor, a motor, an electric motor... go from the scraper and find a thousand ideas and above all real pieces to measure and draw

unfortunately the difficulty lies in finding quoted designs... apart from school texts it is practically impossible! comunuqe are 2 excellent subjects those you recommend!

excellent idea of the electric motor, it is to find an explosion or something like that... for the speech pieces to measure and realize I would say that it is too challenging even if it would be much more interesting:finger:

Monday I take a leap in the library:biggrin:

Look... unless you go to some shop where you know the owner and you pass "sub-banque" a couple of drawings... I doubt he can find something.
you know... it's intellectual property, work fruit and copyrighted
I think the simplest solution is really to go from the scraper, take something, dismantle it and detect it
so you would bring the piece together to the model, for the series "how it is and how others might have thought it" :smile:

hello mbt, unfortunately the problem of today's university is that the prof will not appreciate how much recommended by you.
Trust me, I've been there too (less than 5/6 years ago) and so. indeed, it will have a decidedly opposite effect. . .will be seen as "he who simplified work"

Right ste_unipi?

I believe you:
I never even put a big toe at a university:smile:
but from what I hear and read, I understand that it is populated by emeritus imbecillity....
my personal opinion, who does the teacher should be the top. besides knowing and knowing how to do, should also know how to teach. teaching is a job you should do by vocation, not by filling or by salary
Unfortunately... I don't think so.

I mean, if there's the top button, and I could take it down to burn it, I would.

I have always said that unfortunately in university there are many professors but few teachers. you need passion for knowledge and dedication of matter, but you need a natural gift to convey knowledge, that is to teach.

I, like so many others, are here, very helpful to explain, to help anyone, especially students in their problems and in their projects and we do it "with so much love", because it comes from within. So much so here everything is free:wink:

there would be something to reflect... and not little. but as always beyond us that we question, the others are empty pumpkins and is unfortunately a lost battle at the start.

(I'm sorry, but for years I've been shutting up about this matter and I feel it very but very personal)

returning to the topic...certain teachers would like to send an email to duchies and request the quoted clutch group... as much as you want it to be... bah.

I reiterate the concept of the scraper... take...smonti....mixes...drawings. It goes that in the world of work you will have to do so many times... and the dirty hands you will have more than once.

Once again! However, it is a very stupid 3d modeling test not of technology (which, however, has already made me tribulate in the choice of the project but less badly it has passed :biggrin: ) let's see what I can find on the books otherwise we will proceed to detect something... for the discourse of getting dirty my hands I tell you only can't wait but the university is not the most suitable place for certain things... philosophy so much, practice 0 and then tease you when you come out that you can't even mount a tool in turret or turn a lathe... not to mention the reading of calibers or other tools!

I have to say that in many subjects I have been "self-taught". ..however to students I recommend so much "humility".

When I was a student, some afternoons went to my mechanical friend in the workshop to see the pieces live and, why not, let them explain their operation from him.
When he said, "I'm sorry, but you don't do these things at university? "
I answered: "You are more professor than the professor on these things."

I don't know if even at your university it works like this but the laboratories are as if they were private and dedicated only to some professors.

I must admit that I also had very few but I had them, professors with the capital p.
but they were only white flies.

for the rest I think the most suitable term is philosophy: Some lessons seemed to me like the diatribes of 2000 years ago when he argued whether the land was spherical or flat.

and, believe me, on technical subjects these are intolerable.. The engineer must be more practical than theoretical.
as one of the best professors said he had:
"The engineer must find a result. if then the number came to mind through a dream or after long and endless calculations little matter. In fact, from the economic point of view it is perhaps better if he comes to mind in the dream. "

then it would be even easier to let it pass directly into 3d with the connected tables. . At least you save the job... :mixed:

I found his "decalogue of the engineer" and would like to post it for admiration to the prof. (I would not like to go ot...please censor my message if not considered suitable. Thank you

the decalogue of the engineer
to better clarify the somewhat particular character that is intended to give to this course it is appropriate to focus on some general concepts that are indispensable not only for a proper learning of the engineering profession but also in many other cases of existence. the decalogue (which is then an endecalogue) of the engineer can, in my opinion, be synthesized as follows:
1. attention to hyperstatic systems - if it is not indispensable to always escape, in mechanical engineering, from hyperstatic systems; that means that every engineering system, is it a structure that a plant that a machine, must preferably have the possibility of “respirating” or must have the possibility to do independently something to him of intrinsic but that the designer could not foresee. classic example is the possibility of axial sliding of
ball bearings.
2. what is in pressure sooner or later loses – the corollary of this statement is that the only type of seal that will never lose is that which divides two environments to the same pressure
3. the blanket is always short – that is, if you cover your face, your feet are discovered and vice versa. This means that it is not possible for a project, which it is, to satisfy equally valid all design requirements. corollary is the fact that if a project meets all design requirements then it is definitely wrong from the economic point of view. of course this speech is worth a lot
less in aerospace or military field.
4. always analyze the “informatic” accuracy of a machine or plant – that is the first condition that a machine must satisfy to function properly is to “know” what it must do. Of course every machine will have its own different language and it is in such language that it must be given the information, but it cannot be expected that it does a certain thing if before someone did not tell it in his language
5. There are no difficult things to understand– if one thing seems very difficult to learn and understand
there may be only three reasons in the world that justify this fact:
• who teaches does not understand the subject and is not, therefore, in a position to teach it• those who teach do not want to understand the subject: this condition seems absurd but it is, on the other hand, much more frequent than you think because we often know it is used as a weapon of power and, therefore, it should not be shared
• learners do not want to learn: This also seems quite a contradiction in terms but it is, instead, a very common situation, since our internal mechanisms of psychic defense make us refuse a priori every new idea that could go to scalfire preconceived ideas, taboos, political or religious convictions etc...
6. the number above all – the ultimate goal of the designer is to produce numbers (of course right numbers). the true designer, i.e., must not prove to know how to make very complicated calculations or to know how to set innovative algorithms and methods, but must first give just results. if then these results are the product of sleepless nights at the computer or if they were broadcast in dream by some ancestor does not change anything. The second hypothesis is preferable from the economic point of view.
7. the order of magnitude, as soon as possible – the true designer is what a problem immediately identifies the order of magnitude of the variables in play. This means that the skill of the designer is inversely proportional to tn where tn is the time used for the solution and n grows to the increase of the urgency of the problem that the designer has been subjected to.
8. dimensional analysis should always be done – especially when the problem is complicated. is in fact the dimensional analysis the necessary condition, but not enough, which indicates whether the way taken can or not be the right one.
9. all in nature is in balance – this commandment is nothing but a different affirmation of the principle of action and reaction and means that every system, whether it seems static or evolving, is always in balance because every “action” that is happening to its intermo can not be accompanied by an equal and contrary reaction; this applies, as said, to all systems of this world (mechanical, chemical, electrical, biological, static etc.)
10. first the analogue approach and then the digital one – when dealing with a problem you must first try to understand what it really is, to identify its connections with related issues and contour technologies, to understand its order of magnitude by comparing it with similar machines; only at this point can it be useful to address the “digital” aspect or numerical of the problem in question to “speer” the famous number of which to the 6th commandment
11. historia magistra vitae – the ancient Latin proverb fits perfectly to the field of mechanical design because every machine is always the daughter of some other machine, that is, every family of machines has its own history. this means that before addressing the problem of designing any machine it is essential to inform yourself about life, death and miracles of all previous machines that are somehow similar to her and/or that solve the same type of problems.

and then, in the end, the commandment of the commandments, the son of the 5th; that commandment which the men who are given to power try to deny with all forces but which is, instead, the absolute and inderogable basis of all kinds of knowledge:
never supinely accept the “ipse dixit”I would say that these words are "conserving as a heritage of engineering"

Congratulations! At least someone remembers these things. to someone comes natural even without having read them. to the most part, unfortunately not even learning them by memory serve to transform a human being into an engineer.

However we solved by taking a drum brake that was on the construction book of juvinall machines or something like that. I forgot that it was a targeted exercise to do "top down" i.e. modeling in the environment together using the layout and the blocks... therefore these simple mechanisms lend themselves well.
