4x4 tubular offroad project

[valemaui]

save to all users of this interesting forum. My name is valentine and I do graphic design in an advertising agency. I have the passion for the extreme off-road I am beginning to work on a project for a prototype of an extreme 4x4 (I attach a photo of an American medium to which I would like to arrive). I used some sw 3d sometimes for work but what I would like to do now is a little more complex. I would like to realize with a sw of cad and design an electronic model to verify measures, dimensions, loads of breakage, thickness of materials, extensions, etc. of a tubular frame (in duruminium or anticorodal) to pass then from the project to realization without making a thousand empirical changes and above all avoid the "crepi" to the first test!

recommend the sw that I can do best what I asked and that it does not foresee a degree in nuclear engineering

Start studying a new sw doesn't scare me, although I know that it will be complicated in a correlated way to how complete the sw will be.

to do what you're asking, you need an engineering degree and a lot of field experience. a finite element analysis software does not provide real results if the data provided in the input is incomplete or result of incorrect evaluations. Furthermore, the construction of such a building requires technological knowledge (metal processing, metal processing, welding technologgies) which are not normally included in the software, but are the result of study and application.

If instead I just wanted to use a sw to size the various parts and simulate the movements (e.g. what you see in the photo), could I try to adventure or dismay me?

if the thing remains at model level 3d you can also venture, and any of the modern cad3d should be enough. if instead you want to invest time and money in the company to build a real and working object, I would feel like to scourge you, or in subordinately to be joined by a technician with specific training in the construction of machines.

Hunter from what I saw in your profile I understand that you are practical of these designs. . then I have entered the world of extreme off-road and the national panorama today provides useless means that slaughter at the first challenging climb, or so massive and heavy means that carry 400 cv engines and to overcome a rock take 2 days and 3 winches... here my idea to study a very light but stress-resistant frame to give measurements and a maximum design to the mechanic who will take care of the construction of the prototype. on the web are present American sites selling their projects for $90, but the prototypes they propose are really ugly!

Think, based on your experience that it would be possible to establish a collaboration with an expert of these programs to pull down an already more professional model than I could do?

Can I find him you believe through this forum?

 

[tecnico_plast]

a very, but very complex and challenging project.

Anyway, I'm always happy to see here on the forum a "paesano" :smile:

you can use any modeling software, inventor, sw, pro/e, catia, just to name a few.

As for the analysis, there are as many valid ones, but it is not my field and I do not feel like making names.

Good luck.

... here my idea of studying a very light but stress-resistant frame to give measurements and a maximum design to the mechanic who will take care of the construction of the prototype. ....

I don't ask anything about cars, but what you said is not that it's just a banal thing. . .

.... on the web there are American sites that sell their projects for $90, but the prototypes they propose are really ugly!

....

Sincerely, for $90 it would be to be taken to flight. It was nothing but to see that others do. or find a technician who supports you because he has passion and likes the game or that figure you burn it in a couple of hours.

Good luck.

technical_plast is also my pleasure in the forums I attend. . .
But for more reason than we are Pakistani, could you not help me in this adventure? ?

I can explain the constructive bases and why of some choices, but the "transduction" must be made by a technician who knows how to use the sw....

the American site I mentioned is this http://www.azrockcrawler.com/_images/plans/plans.html for $90 they send you the explanations of how to build the chassis and dvd with the detail "pass step" ... but the means are really ugly and old-fashioned. . They are also based on very heavy pipe sizes by providing very heavy engine housing.

for sail... I believe that starting to throw some realization base you could also push your mind to think of selling the project to those who asked, considering that in Italy this type of medium is taking foot and the only reliable sources are the American ones, but not all have $10,000 to import a frame from the uses.

all interesting and curious.
I know little or nothing about the subject.. offroad yes, but strictly to 2 wheels :biggrin:.
I'd just like to tell you to drop "unsuccessful" studies on aluminium alloys (at least these "amateur" levels). remains on steel; there are excellent characteristics known and "controllerable" and for these achievements still remain the best choice.
if your bran is just the weight do not think of saving who knows what, indeed.. The best steel frames are lighter than the best aluminium rivals.
the choice is made according to a thousand other characteristics, the weight passes in the second floor (for differences of few etti).
considerations that are valid if you really look for a car "from war", if you need to go to the bar in the square on Sunday morning the speech changes.

greetings
Marco:smile:

remains on steel; there are excellent characteristics known and "controllerable" and for these achievements still remain the best choice.

In addition, if there are accidents, steel is "around". never underestimate this aspect. the materials that are accumulated absorb the energy that would otherwise be absorbed by the driver.

 

[valemaui]

in the field of rock crowling or extreme off-road that you want is now used for several years in use the anti-rodal... here in Italy I have seen some parts of some prototypes made with the adional.. In both cases they behave egregiously, indeed they are used precisely for their characteristics of rigidity and lightness. . .

and still allow me... the specific weight of the traditional steel varies between 7.5 and 8 7.8 kg per dmq.... the seasonal or duraluminum that you want is 2.7 (source http://www.engineerplant.it/tab_metalprop.htm) or about a third... or 100 kg instead of 300 only for a rollbar cage.... Therefore at the cost of correctly dimensionalizing it an aluminum structure should weigh less than one steel

Moreover the maximum stresses are on the bridges and arches that connect the shock absorbers to the bridges themselves.... that for safety you could make in steel, as well as the base of the motor... but it is all theory

there is also another material used always in the use of the dom (http://bulletproofsteering.com/tubingspecs.html) pipes obtained from the full... this is an example of chassis made with this dom and sold ready to be assembled ( http://www.polyperformance.com/shop/poly-performance-dual-sport-2-seat-chassis-p-1352.html )

:d marco to go to the bar on Sunday I walk... the middle can not circulate on the road!!!!!! In the end, only this must be done:

Oh, yeah.
so is true
However, aluminium also holds a third of steel stress. . .
So... the accounts aren't so discounted.

Therefore at the cost of correctly dimensionalizing it an aluminum structure should weigh less than one steel

However, the aluminium elastic module is also a third of that of steel, so in order to have the same rigidity in tensile or compression-driven structures (as are the typically reticable ones) you should triple the section, valuing the weight savings and finding yourself more 'with the technological problems given by aluminum, such as the difficulty' to weld or the absence of a fatigue limit.

aluminium is generally used for canned structures where the main stresses are bending or twisting. you could get the same rigidity values even with steel, but you would go down to thicknesses such as to create big welding problems and ease of storage.

 

[valemaui]

considered very interesting... I'm sure I know the plates and bars are all made of aluminium... for the frame then I want to study better this dom steel which is used in the use, hoping to find the technical characteristics to compare. . .

However, the dilemma remains of how to build in 3d this chassis...

I assure you that this is the last of the problems, is what there is before it should worry.

I have visited the world 4x4 in the 86/92 years (since you could go everywhere and until, thanks to the morons going everywhere, they destroyed everything) I ask you: where do you think you can use such a means?

Try to lay those rhotons on some pietrons and find you in prison ( sorry, it is always the poetry of bonds that pervades me and guides my fingertips)

Bye.

 

[valemaui]

stefanobruno I entered this forum to seek help in the realization of the plan of the medium, where to make it turn is another problem.
here in Sicily only my club organizes 2 races a year dedicated to these monsters of the offroad... other clubs do the same....all strictly on private grounds and without giving damage to nature... for absurd a means so far less damage of a common pajero that on Sundays is improvised and goes for fields to tractor everything that finds on its way (until when it is not instilled )

 

[valemaui]

reading also other posts on tubular frames in this forum I took into consideration using catia v6 as development software... I think it's one of the best... Can someone tell me if I'm wrong, maybe suggesting the best solution?

But... do you want to buy catia v6 to make the frame? catia v6 costs as much as the frame with an extra zero at the end.. .

if it is for purely philosophical speculation, why not throw on alibre? So if you realize you've beaten the big one, you'll have only €100?

However, if you want, do a sketch on frame paper, anyone in this forum can draw it in ten minutes, and if you don't find anyone, I will design it for you.

 

[Fulvio Romano]

Does anyone explain to me that they're these pipes drilled from the full?
which serve, because they are "better" and because at the end of the page the pattern of a normal mannesmann is reported.
I think it's a little crab to be light. . .

Besides, valemaui, I ask you a question that may seem stupid: because in the design of a vehicle you focus so much on the chassis, starting from this?

I think it's like designing a house from the wallpaper.
