how to find Torque produced in shaft when pressure applied on the plate attached to that shaft

Hello,

 

I am working on model of pressure plate which have axis offset. A shaft passes through it. when pressure applied (in x-y) on the pressure plate due to the offset one side of pressure plate will have more pressure. Which causes rotation on around z axis. As the shaft passes through z-axis. Shaft and pressure plate are bolted. As pressure plate will rotate it will tend to rotate the shaft. I want to find out for particular pressure how munch is torque is generated.

 

Preliminary analysis:

i have made freeze contact between shaft and pressure plate. Gave dof only z rotation for the shaft. Applied pressure on the plate. I have got only stress and deformation. No angular movement in shaft.

 

 

How to solve this problem

 

Thanks.

    Hi Teja,

     

    Can you share the .fem file, please?

    Hi,

     

    thank you for sharing the file.

     

    You have constrained the shaft in 3 translations and 2 rotations. Since solid elements don't have any rotation Dofs you are not seeing any effect of the load.

    Think about creating 1D elements at the ends of the shaft which allows rotation.

    hello sir,

    we have tried creating a point at center and connected that point to shaft using rigid elements and gave dof to that point. But we got deformation in e9.

     

    what to do now.

     

    Thanks
