有关惯量主轴的计算方法

The Calculation Method on Inertia Spindle

质量分布均匀且几何形状对称的刚体,其惯量主轴可以由刚体的对称性很容易求出。对于一般性的刚体的惯量主轴而言,可将所求的惯量主轴转换为线性代数中求特征向量的问题,从而求出。

The inertia spindle of uniform mass distribution and geometty of the symmetric rigid body is very easy to find by the symmetry of the rigid body.For general rigid body inertia spindle, the calculation of in-ertia spindle was converted to the problem of sol, ing eigenvector in linear, thus obtained inertia spindle.
