摘要
转动惯量是研究刚体运动规律的一个重要物理量,椭类形状刚体的转动惯量的计算十分复杂。本文利用惯量主轴法巧妙计算了椭类刚体绕过质心转动轴的转动惯量,给出了参数表达式,对大学物理教学有一定的促进作用。
The moment of inertia is an important physical quantity for studying the law of motion of a rigid body. The calculation of the moment of inertia is very complicated for the elliptical rigid body. In this paper, the inertia principal axis method is used to calculate the moment of inertia on the elliptical rigid body around the center of mass, and the expression of the parameters is put forward. It has a certain promotion for the college physics teaching.
