Hi everyone,
I have a cabinet (attached file) and I want to drop from a height of 400mm.
I came across the Nonlinear Transient Analysis with ball exercise but it doesn't seem to be of use in my case or I don't know how to do it.
Can anyone help me in this case.
Thank you very much

We would be glad to help you. What aspect of the Ball Impact Exercise are you having problems with? It is essentially identical in concept to your model.
Also, I think that some of your 278 contacts (Separation/No Sliding) are not what you want to use. Some of the components are glued together, correct? Those should use bonded contact. The other parts are probably stapled, glued, or screwed together. I would use bonded contact for those, too. In fact, I would make everything bonded contact. Replace all 278 contact with one "Solver Contact" set to Bonded type with an activation distance of 1 mm.

Thank you very much for your prompt reply John,
My client also needs an additional type of analysis like this:
There is a table as the attachment files, They put 50kg force near the edge of the table. They want to know if the table has fallen?
So what kind of analysis do I need? If so can you have specific instructions for this type of analysis?
Thank you,
Hao

Hi Hao,
Why would the table fall?
