摘　　要：针对力传感器动态校准及溯源的问题,介绍了两种常规的力传感器动态校准的方法,分别建立了不同校准条件下力传感器的运动方程,说明了不同校准条件下的结果差异性。然后介绍了一种基于高精度的基于刚体碰撞的脉冲力发生装置,说明了装置的结构与工作原理。同时说明了采用外插式干涉仪测量的方法。最后进行了利用本装置对力传感器进行实际校准试验,并对结果进行了分析,说明了本装置校准结果的可靠性。Aiming at the problems of dynamic calibration and traceability of force transducer, it introduces two most used methods for dynamic calibration of force transducer, and different motion equations for force transducer are established under different calibration conditions, and illustrates the differences of different calibration results under the different condition in this paper. A high-precision impulse force exciter based on rigged body motion is introduced, illustrates the structure and working principle, the methods of using a hetero dyne interferometer. Calibration results obtained by the device for a chosen force transducer are given and further analyzed, and the reliability of calibration results of the device is affirmed by the results.
