摘　　要：利用有限元法建立了力传感器的动力学方程。利用该模型就各因素对传感器动载输出的影响进行了仿真分析 ,从而对检疲劳机动负荷用力传感器“静标动用”The dynamic equation of force transducer is set up by using the FEM in this article.The simulating analysis of several effects on the dynamic output of transducer are made interms of the model.And then the knowledge of the error which is caused by calibrating statically while using dynamically of force transducer for calibrating the dynamic load of fatigue machine is acquired.
