Paper Abstract

A model of the compound pendulum used for measurement of micro impulses is presented. The effects of pivot friction, air friction and vibration of the stand are simulated through numerical method. To improve the measurement accuracy, it is concluded through the simulation results that the natural period of the compound pendulum should be greater than twenty times the time duration of action of the force being measured. And the moment of inertia of the compound pendulum and the pivot friction should be properly decreased to get a better sensitivity.
