Study on Modal Analysis and Dynamic Performance of Electric Wheel Self-Dumping Truck Carriage
In view of the reality that the transport efficiency affected directly by fatigue failures on a carriage of a electric wheel self-dumping truck in running process, in order to inquiry the failure reason and study the relationship between the dynamic performance of the carriage and the natural frequency of the carriage, ANSYS finite software was used to analysis the dump truck carriage model created by PRO/E in the paper, the low-level frequency and the vibration of the dump truck carriage were obtained, and the carriage’s dynamic performance was studied with the verification principle of reducing the amplitude of frequency response function in resonance. The results show that the road surface excitation greatly affects the dynamic performance on the compartment floor, and the road surface excitation, which should be avoided, is the main reason of fatigue failure on the carriage.
