motion simulation

[LucaID]

Hello everyone,
I need to calculate the specific weight of a 3d model without resorting to classical methods (paper, pen and mathematics). I heard that sw is able to calculate such data and create motion simulation.
is someone so kind to explain to me step by step how do you simulate the movement of the piece I attached?
I need it for the thesis... please help me! ! !

hi lucaid, I changed your message and I inserted the pictures as by regulation. pictures must be inserted by going into the advanced mode with attached management.

for your problem I tell you that solidworks is a solid modeler and when you create a model you just make tools-> mass properties to see mass, baricentre, inertia, etc...
if when you model solids check the right density you find yourself with data very similar to reality.
for simulation: what do you need to see? only the width of the angle? Do you have to see the yarn or can you even calculate the inclination?

thanks for correction.
The fact is that sw I can't use it just. simply amount the model created on rhino and then stick the materials. I would like to understand just how I do, always if possible, to see (not read, also because I would understand little) how tilts that piece without and with the counterweight. .

 

[LucaID]

ops, I didn't read the last two lines
Let's say all that information you said would be very useful to me. .

I attach a simple set with a model similar to that of your images. the "donder" and the counterweight are bound together but are completely free compared to the plan. if you start the simulation you will see that the models go to the unbalanced plane towards the counterweight, which I set with a specific weight 5 times that of the "donder" (I don't know how loop to call it that yellow thing:smile: )
If you change the specific weight of the counterweight and recalculate the simulation you will see that the orientation of the two united components changes.
similarly if you suspend the counterweight and recalculate the simulation the pendulum rests in tilted balance from the opposite side.
if you connect a sketch with reference odds you can also immediately view the modified corners. Alternatively, use the measuring instrument and control the corner.
I did it in 15 minutes, without the cinematic simulation module that I am convinced can also optimize everything according to project constraints.

I read that you can't use swx at all, so there's little to explain step by step. You need to get a good buzz and learn to use it

I need it for the thesis... please help me! ! !

to more reason you have to learn to use it. here you find all the help you want, but the abyc you have to put it on your own, that besides that of swx is very easy and of the help you have of advance.

Hi.

p.s I rocked with an ellipse seeds then I wanted to bind it tangent to the plan to start the simulation. I realized that the surface of the semiellisse cannot be used for any type of bond
It's weird. .

 

[LucaID]

Oh, thank you! I took the file you attached to me as a model. .the problem is that my piece just starting the simulation flies in the air :s I tried to change the parameters of gravity but nothing..in another case the piece goes down passing the plan. Are there any other parameters to be touched?

if you indicate the direction and the right direction of gravity it is impossible that you fly up. Remember to solve the components, if you use them light weight the simulation is faked.

In another case the piece goes down by passing the plan.

if the plane, solid or both are passing surfaces one within each other. you have to work with solids
but did you use the axieme that I posted to you or imported from rhino?

 

[LucaID]

strange, it is set on the y axis down. cmq I imported the various pieces individually from rhino, then I saved them in sldprt and I created the axieme by inserting all the elements. I think that's the right procedure. .
If you want/you can attach the file so take a look at it:mixed:

if you have exported to iges you have surfaces and swx you keep them so as to save in sldprt, unless you confirm when you ask to try to form the solid. If the sup is closed usually works, otherwise you have to do it later.
Alternatively you must export as solid from rhino.

I can't understand why you dare to work twice. If solids are similar to those you posted does not first shape them with solidworks? you have to learn only to extrude, it will take 5 minutes of tutorial.

I add that if he corrected the profiles and mass properties of what I posted to him he would have the beautiful asses that he did.

..it is true that I asked for help on this forum just because I never used sw. I will learn!! :

mmh...rhino...dondolo giallo...contrappeso color acqua...

two plus two, isn't that you're looking for metacentric evolved? It seems to me that the approach of marcof is not suitable for this because it does not consider progressive filling... there are rhino plugins that do it, there is the hydrostatic package, but I would not be able to help you more than so.

But maybe I've been hypothesized. . .
