惯量主轴在计算均质刚体转动惯量的应用

The Principal Axis of Intertia by Using the Rotational Inertia of Uniform Revolutional Circular Cone is Given as a Special Example

均质刚体 ,可根据其对称性来确定惯量主轴以及中心惯量主轴 ,运用惯量张量 ,可方便地计算通过其坐标原点的任意轴的转动惯量 ,本文以均质圆锥为例来研究这一方法的应用 .

The principal axis of intertia about uniform revolutional rigid bodies are simply calculated by using the method of rotational inertia tensor,the article introduce that the method of rotational inertia tensor is used to the uniform revolutional circular cone.
