摘　　要：转动惯量即刚体绕轴转动惯性的度量,是刚体力学中的重要概念。本文从刚体转动的动量矩和转动动能定义出发,推导计算了几种形状规则刚体的转动惯量,推导过程通俗易懂,便于学生理解和掌握,并且有助于学生寻求创新途径去巧解各类刚体的转动惯量。Moment of inertia is used to measure the intertia when rigid body rotate around the axis, which is an important conceptin mechanics. This paper, from the definition of moment of momentum and rotational kinetic energy, calculated the moment of inertia ofseveral regular shape rigid body. The process is easy for students to understand and master, and can help them in exploring the new approach to solve this kind of problems.

关 键 词：刚体 转动惯量 推导
