Frequency content analysis of a dynamic system load histories by an example of the dump truck frame is considered. Truck and its subsystems natural frequencies and mode shapes were determined with the use of CAE simulation methods. Simulation results were used as source information in spectrum analysis for the load history length determination of most damaged frame locations. Also, power spectrum density function maximums of load histories were described based on these results. Approaches, considered in article, can be realized for different dynamic systems.
