study of movement

[MARCOC]

hello to all, I was trying to use the ambient of solidworks animation, and I came across the command "contact between solid bodies", then I made a blind with 2 pieces to try to understand how it works, I applied a linear motor to one side, the other fixed seal, I activated the contact between bodies, the anointing animation, but the moving part does not feel the contact of the other body,

Does anyone know if it is possible to do this or the contact command works otherwise? ? ?

Thank you very much

hi to all, instead of using a linear motor, I activated gravity and contact in that way works, but now I have another problem that I do not return the actual quotas on the final position of the part after animation, I put image for clarityI would expect that the final qupta between the 2 centers is 2.75, instead the 9 round stops slightly earlier, I am using "basic motion", someone knows how to give me clarifications on where you can act to be able to have the exact contact between the two rounds? ? ?

Thank you very much

could depend on which side is gravity, the density of the materials...maybe a piece is to 1. with basic movement however accuracy and real options are different.

calculates that if I use the command moves with the check on "dynamics", the contact and perfect,instead of the animation I get high the odds

then I press that it is a topic at least for me very complicated; in the presentations show you that the simulation part is a very simple pussy that even a fool could use but then it is not so.....
Comuque. in the two posts you first used the study of movement then the basic movement are two very different things; I have always used the motion study to do small analyses.
the solid contact serves to "block" and to define in phase of study of the movement the pieces that do not or have to connect with each other, below you find a lot of options and usually solid puts as default material a plastic material, that is why you find differences of quotas, and therefore malleable changes the option in steel with fat and you will see that the results will change and approach reality.
Plus you can't put two pieces in space without binding them.
the piece you fix is fine so, but the other I make a kind of guide so that it is guided against the other piece otherwise you run the risk that you move a little at home.....repeto is a very complex topic, I when I do studies I harm myself of holy patience and usually take care of several days of tests and verification......

hi teseo,si the title of the discussion takes the name from here I put imagethen once you activate the environment you can choose 2 or 3 options (if one has the active motio)
and that's why I wrote "basic motion", using basic movement on the contact there are no options on the impact or materials to choose (which instead choosing "movement analysis" yes, in this I expect and correct that the share is not the theoretical one, because the damping and rigidity of the material come into play) so I expect that the contact is a physical contact to 0 and instead not.
later place the assiemino so you see how I have bound the pieces (of course the tondo has as degree of freedom only the axial movement)

I take advantage of the 3d to ask a question:
In these days I'm trying motion to simulate simple mechanisms, for the part of cinematics I think everything ok, I find myself in greater difficulty on dynamics for example for the simple simplified tavellism of which I attach the screen if I applaud a motor and a couple I can not blow out the force on the forward. or is it limiting?

View attachment 52356or is it limiting?

It is not absolutely limiting indeed it is a very useful tool only that to know how to use it you have to have so much time and then use it very often if you use it like me two three times a year here is a nice problem....army holy patience and all the times you solve a problem mark it. ...
