1. ## Contact modeling of gears

Hi, 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?

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.

4. ## t-connection error in motionview

I am doing MV-1010-contact simulation tutorial of geneva model. When i checked the final model the page prompted an error in the model as: "Error: Contact Crank_to_slotted under Model from HM references one or more graphics that contain free edges, i.e. the geometry is not closed, or T connections. The graphic(s) in question are: Crank, Slotted Disk. Open shell graphics or graphics with T connections are not allowed in contact simulations. " I think i need to delete or merge free edges, but i don't know the procedure for doing that. Please help me in solving this issue? PFA the model file
