| 为研究过载-振动复合条件下加速度计不对称性引入误差的影响，建立了包含加速度计模型不对称性的振动整流误差数学模型，并给定相关参数进行仿真分析。分析结果表明，当过载大于等于振动加速度幅值时，可忽略加速度计不对称性引起的振动整流误差；在给定的仿真情况下，当过载小于振动加速度幅值时，加速度计不对称性引起的振动整流误差小于全部振动整流误差的1%。 |
| 英文摘要: |
| 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. |
