| Abstract: | To corrctly establish the motion differential eguations of multi-degree of freedom linear vibration system is an important step in solving the vibration problems of multi-degree of freedom system. It reguires to correctly establish the inertial matrix, stiffness matrix and damping matrix. And how to find these three matrixes above-mentioned in a forthright and correct way has been discussed in this paper. Use of D'Alembert's principle and general theorems of dynamics to set up the inertial matrix is the emphasis of this paper |
