design of a mechanical piece

[Egervi93]

Hi, I'm a mechanical engineering student. I have to carry out a project in 2d and 3d of a mechanical piece of my choice, which is not taken as a piston or a biella. Do you have what to recommend? It must not be too complicated and not even so simple to carry out. I expect your advice, thank you in advance!

 

[falonef]

you have my time a good example was a piece of worked cast iron

 

[meccanicamg]

can be an electro-welded and milled carpentry for machine tools, gears of a gearbox, a water bottle. . .
a lifting hook.

a classic of the classics is the sizing of a reference tree.

Starting data: power to transmit, transmission ratio.

at the end it is:

1) calculate the bending and twisting shaft
2) dimensioning/choice gear module
3) choice of bearings

other classic is a coupling flange for a hydraulic cylinder

given the shot of the cylinder and its inclination, dimension the flange (a welded).

therefore it is a question of dimensional welding cords, flange pin and possibly in bolted connection that binds the flange to the ground.

are standard and classic exercises of state examination or the "machine construction" course of the old orders.

or do the "creative": dimensional a handlebar of a mountain bike (think how it supports the hands on the handlebar, the direction of the arms/direction_forza, a nice design taking cue from the bike home)

examples are vague.

a good starting point are also the classic exercises carried out for mechanical experts of class v (see also the themes of examinations
maturity: of snacks you will find at iosa!).

parts from there and add the level "university", maybe something design to fatigue.

or go to the "cinematic", biella and manovella taking into account the dynamic forces.

Here, maybe check the size of the crick lifting your car: the constructive details and the odds you find them underhand! ! ! !

Say hi, go.

ehmmm... you said project, so I assumed part of dimensioning/choice materials.

or is it for a drawing course?

(so the attention moves on the table with all the crisms: tolerances position shape, exhaust gorges for machining, welding directions etc. etc.)

Hi.
When I was working in cagiva, the proof that was made for the recruitment was to draw an aspiration duct of a monocylindrical motor, it was given the departure and arrival and the encumbrance (usually the shock absorber) and a day of time.
in one day, of course you could not finish it also because then it was designed to the tecnigraph, but you could see how the work and the degree of precision and the solution conceived was set.
Today, with the tools in possession, in one day you can see various solutions, ready to be realized in rapid prototyping and the day after having the piece in hand to be mounted.
If you want me to send you an example
Hi.

 

[falonef]

you would like to have the example in pdf or better cv5 file

 

[Pierandrea58]

But you didn't ask
Am I wrong?
Swiss where?

No, it was not me.

Now that I'm still going because we're talking about Swiss.

falonef, but you work in the watch industry?

But I don't want to go too far.

show!!! and you never said that?

Well, was it enough to look a little better at his avatar no pier?
