Simulation Time for Contact analysis

Hi,

 

I am Simulating motion analysis of a mechanism in which the motion is transmitted from Gear Trains to Lead Screw to lever attached with Spring of high stiffness. I have given Contact between Gears , Lead Screw Mechanism. i have given simulation for few seconds but it is taking too much long time for analysis.

 

Can anyone suggest me how to make simulation faster.

 

thank you

    Hi sir, I am doing spur gear to spur gear transmission analysis on motionview (gears have module 1 & teeth of the gears are 28 and 82). I used the rigid to rigid type gear contact and used poisson model with parameters as ,penalty = 1000, COR = 1, Normal transition velocity = 1mm/s to define the contact. I gave uniform rotational speed to the gear with 28 teeth and i requested for the output of rotational speed of the gear with 82 teeth. Theoretically i should be getting output plot to be a straight line with slope 0 & 1.024 rad/s (marker velocity) above x axis (time), but i am getting a curve which is not throughout straight line, plot shows a max peak of 7 rad/s velocity as well.

    What could be the issue for this?
