椭圆环形刚体转动惯量的数值计算

摘要

By use of Matlab we calculated the rotational inertia of rigid elliptical ring numerically and find a polynomial expression to fit the rotational inertia of rigid elliptical ring , consequently the rotational inertia of rigid elliptical ring can be calculated quickly.%用Matlah编程对椭圆环形刚体的转动惯量进行了数值计算，并拟合出了椭圆环形刚体转动惯量的多项式表示式，从而可快速计算出椭圆环形刚体的转动惯量．
