Abstract
In a vibration damping device, the moment of inertia Jof a driven member, the moment of inertia Jof an inertial mass body, the mass m of crank members, the distance L3 between the center of gravity G of the crank memberand the fulcrum of swinging of the crank memberwith respect to the inertial mass body, and the distance L4 between this fulcrum and the center of rotation RC are determined so that torque fluctuation of an object for which vibration is to be damped, which is derived based on angular displacement and angles obtained by solving an equation of motion for the driven memberand an equation of motion for the entire vibration damping deviceis equal to a target value.
