This study evaluated the dynamic safety of a controller-integrated servo motor. The evaluation used transportationand operation vibration profiles based on the U.S. military standard code MIL-STD-810G. The convergence trendof the equivalent stress owing to a concentrated load was tracked to determine the reliability of the finiteelement model. The weakest parts were detected in the integrated servo motor with its operation frequency bymodal analysis. Furthermore, the dynamic safety of the integrated servo motor under transportation and operationvibration environments was evaluated by random analysis. Notably, the equivalent stress caused by each vibrationprofile was significantly lower than the yield stress of lead, which was the weakest material in the system. Thefindings show that the proposed numerical test procedure can be utilized to verify the durability of trackedmilitary vehicle designs.
