integratori motion

[Gio_RS]

I must realize a rather articulated motion, where the linear motion from a rack is transferred to a spool, then to the ball bearing calettato on the spool itself. I did some tests,spezzando the motion.... before trying the motion only of the rack and the rocchetto, then I tried that of the bearing.I did not find mistakes, everything works. However by starting the full motion,soliworks begins to make calculations but does not proceed, remains as to say blocked, always at the same point (using gstiff as a supplement). then I tried the wstiff supplement and things improved.I did not try the si2_gstiff.
(I also consulted the online guide of the program)
According to you this wait is due to the slowness of calculations,or is the gstiff supplement not suitable in this specific case? ?what supplement is most suitable? ?

Hello,

I don't remember how motion works in sw, but anyway we talk about solutore adams (although old man), and then things are not very different.

in any case is your mechanism a cinematism? or do you have 0 degrees of freedom?

in the case of cinematism, gstiff is the best solutor, in the case of system with degrees of freedom, wstff is better, then si2 if you have functions (forces, contacts, etc) that make you change dynamic actions internally to the system.

this to great lines.

Does your system get stuck but does it progress or does it not go ahead?
if you do not go ahead furnace actually you are stuck.
Do you have any info/ error message from the solutor?

bye

the system presents degrees of freedom. the problem is that it doesn't report errors when the calculation starts, only that while processing the accounts I don't see proceed the bar moves a few mm; not only,trying with wstiff I can complete the simulation and also see animation,the strange thing is that I can only sometimes,because most of the times it freezes as said at first.
how is it possible that by doing the same procedure,with the same settings sometimes I end the simulation and others not?? yesterday I tried for hours and didn't go, in the morning he started to the first blow....

I think I have identified the problem, probably a couple of coaxiality of the inner ring. . . coupling it with the origin did not like it, better to couple it with the axis of the tree on which it is calettato.strano however that it did not report errors.... .
