In order to investigate the influence of accelerometer error due to asymmetry coefficients in overloading-vibration compound environment, a mathematical model of the vibration rectification error including the accelerometer model asymmetry is established, and the simulation is carried out with the model and given values. Simulation results show that the vibration rectification error induced by accelerometer asymmetry coefficients can be omitted when the overload is no less than the vibration amplitude. Otherwise, the vibration rectification error caused by accelerometer asymmetry is less than 1% of the total vibration rectification error.
