NX7.2 Motion Kinematics - how to display required torque for mechanis
(OP)
Hi
when I have a mechanism and have everything linket up and I am displaying speed, displacement and forces in joints and on markers.
How do I calculate the required torque to drive the mechanism?
On the siemesn PLM NX website is a demo video of an aircraft wing mechanism for operating the flaps. However they display torque over time.. I only managed to display displacement and forces over time.
Would I really have to add a PDCM motor driver and then someohow get the torque of the motor? How do i know what the settings and starting values for the motor are?
Normally I design a mechanism and which resulting massed, speed, intertia etc I get a required torque which I then use to look up a motor that is fit for the job
I need urgent help on this

I imagine you have already thought of this, but you may find a solution using Expressions - given that you know the forces and the geometry, you should be able to calculate the torque in the same way you would do by hand, in a T=FxR fashion.
I realise it's not the quick solution you were probably hoping for, but in the absence of any other replies I thought I'd add it in case.
