Why nonlinear dynamic simulation show vibration the acting forces already fixed.

Hello

I not familiar with SolidWorks nar simulation.

Now I'm try to run nar dynamic simulation on a gantry structure.

Even the acting forces are fixed it shows variation on displacement graft.

How to done this simulation correctly.

 

01. the structure which irun the simulation.

02. How i have apply the force to middle of structure.

03. Result.

In my input there is no variation of force til 5 seconds. But the graft show vibration.

Relevant file attached with this.

Thank you.

Udaya.
