The vibration fatigue reliability of AMT actuator is one of the most significant performances of AMT.For acquiring the accurate and efficient analysis and evaluation of AMT actuator vibration fatigue reliability

the AMT actuator actual driving road load spectrum are collected in Dongfeng test field

combined with the developed AMT actuator multi-axes road simulation test bench

the load spectrum simulation iteration method based on remote parameter matrix control with time-frequency domain error weighting coefficients 0.5respectively succeeded in achieving accurate and efficient reproducing of AMT actuator actual driving road load spectrum and thus road simulation excitation spectrum are extracted.By using the finite element analysis soft HYPERWORKS and multi-body dynamics simulation software ADAMS

the virtual rigid-flexible coupled road simulation test platform is built with reference to the actual AMT actuator multi-axes road simulation test bench.Simulation analysis is conducted with the achieved road simulation excitation spectrum as input and the outcomes are verified by actual collected spectrum and road simulation test results

thus the virtual vibration test method for AMT actuator based on road simulation excitation spectrum is established

an effective approach and method for AMT actuator vibration fatigue reliability assessment is provided.
