A Software Used to Calculate the Moment of Inertia of a Moving Structure in a Relay

继电器动态特性研究关键问题之一是转动惯量的正确计算。本文用直角网格的数值解法，计算复杂几何形状物体的转动惯量，包括数学模型、求解原理、程序框图、计算实例。

Calculating the moment of inertia correctly is very important for studying the dynamic characteristic of a relay. This paper introduces a software used to calculate the moment of inertia of a body which may has complicated geometric shape by using right-angled meshs. The mathematic model, calcutating process, program flow diagram and examples are given in this paper.
