摘要: 根据转动惯量的定义,提出了计算转动惯量的质量投影法,应用质量投影法讨论了六面体、椭圆盘、圆柱、圆台等几种特殊形状均质刚体对转轴的转动惯量.

关键词: 刚体, 转动惯量, 质量投影

Abstract: According to the definition of rotational inertia,the mass projection method is presented to calculate the rotational inertia.The rotational inertia of some special rigid bodies such as the hexahedron, the ellipse plate,the cylinder and the frustum cone are discussed.

Key words: rigid body, rotational inertia, mass projection
