Frequency, impact and drop tests are all covered within dynamic analysis. The primary unknown in a dynamic analysis is component displacement over time, but with this calculated, stresses, velocities, and accelerations can also be determined together with the natural modes of vibration.
SOLIDWORKS Simulation makes use of one two methods when conduction dynamic analysis:
Linear modal analysis which is able to calculate natural modes of vibration and then the displacements, stresses, strains, velocities and accelerations
Nonlinear dynamic analysis calculates the displacement field at each time step taking into account the applied loads and initial component velocities, following this it is able to calculate the nonlinear stresses, strains, velocities and accelerations
