| Abstract: | A method for transforming acceleration and velocity in inertia system to non-inertia system is presented based on rotor theory. Then the acceleration and velocity equation of flexible multibody is derived.the dynamic equations of flexible multibody are obtained based on the Jardon′s principle. An numerical example is given, it shows that computer storage of our method is much less than other methods in calculation. |
