Hi

I have a question regarding the dt timestep of an impulse load as discussed in the following video:

He uses dt=10ms. If we set dt=8 or 9 or 11 we get widely different values for Fmax.

Thus, a lot of such impulse loading boils down to the correct selection of dt.

I was wondering if anyone knows of a way or a more advanced method for reverse engineering a system to obtain dt? I have a system that includes a dt from impulse loading and as discussed above get very different results for small changes in dt.

Any help greatly appreciated.

Thanks

Graham
