刚体对空间任意方向轴转动惯量的理论计算

Academic Calculating of Moment of Inertia on Rigid Body to a Spatial Axis with Arbitrary Orientation

文章就刚体对空间任意方向轴的转动惯量的计算问题进行研究,利用高等数学的知识推导得出一般计算式,并讨论两类有特殊规则外形的刚体对空间轴的转动惯量的计算问题。

The article mostly makes a study on the calculation problem about the moment of Inertia of a rigid body rotating around a spatial Axis with the arbitrary orientation by the knowledge of Advanced Mathematics,deduces a commonly formula to this problem,and then discusses two kinds of rigid bodies with regular shape.
