摘要
确定了任意匀质边框三角形刚体的质心的几何位置;在此基础上推导出匀质边框三角形刚体绕质心轴的转动惯量公式,为计算三角形网格状边框刚体绕质心轴的转动惯量奠定了理论基础.
The center of mass for an arbitrary and even triangular frame is determined by using pure geometrical method ; based upon it, the rotation inertia formula of a rigid triangular frame about its center-of-mass axis is derived; and thus lay a theoretical foundation for the calculation of rotation inertia about a grid-like rigid body.
