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.
In my input there is no variation of force til 5 seconds. But the graft show vibration.
Relevant file attached with this.
