i want to perform a dynamic analysis where a sinusoidal force is applied on the axles of a semi-trailer. the semi trailer model is initially subjected to static loads. first i performed static anlysis then a modal analysis to extract mode shapes and natural frequencies. in modal analysis i used static structural as pre-stress.
the purpose of the simulation is to investigate the occurance of resonance when the force is applied. i tried a transient structural analysis but i don't know whether it is the right choice or not. if not what type of dynamic analysis shoud i perform? and how can i know whether resonant vibrations occur or not?
can anyone help me please
