Hello Peter,

Thanks again for the input. I did 2 trial fatigue analyses.

In the first trial, component 1 will rotate back and forth ( 2 steps), and as it rotates, it will push and pull component 2. i observed some stresses in the component, but in the fatigue tool, I am finding the component’s life to be infinite.

In the second trial, component 1 will rotate only in the clockwise direction. I observed some stress in this too, but now the fatigue tool is showing varying life across the component.

I don’t know why for one trial I am getting infinite life and for the other I am getting finite life. How to attach the workbench archive file in this post. I can share the workbench archive for this.

Thanks & Regards,
