Microdynamic test refers to: the measured body dynamic moment M, the moment of micro-power A, the instantaneous micro-power P, and their maximum and some related parameters of the measurement. The measuring method and the principle of the testing instrument include the strain type micro-force sensor and the force-torque conversion mechanism. In this paper, the design of micro-force sensors, the derivation of experimental results and the experimental data are given. The working principle of the speed simulation system is specially designed according to the characteristics of the micro-dynamical test. The overall structural principle of the instrument is tested. Finally, the measured results of some micro-precision mechanisms .
