Latch modelling
Latch modelling
(OP)
Hi, I am looking at the modes of the automotive closures in installed conditions using FE model. The latch stiffness is critical. Has anybody got any stiffness numbers(spring rates) for a fore aft,vertical and lateral stiffness taht can be used in the analysis.
Has anybody got any idea of range of frequency of the closures that one might expect closures.
Other ideas welcom

2000-5000 N/mm and 0-250 Hz would be my WAG

His answer, oddly enough, will be to go to talk the modal analysis people. Without correlation data his model will be rubbish, as will yours.
