Abstract
In a vibration damping device 20, the moment of inertia J1 of a driven member 15, the moment of inertia J2 of an inertial mass body 23, the mass m of crank members 22, the distance L3 between the center of gravity G of the crank member 22 and the fulcrum of swinging of the crank member 22 with respect to the inertial mass body 23, 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 member 15 and an equation of motion for the entire vibration damping device 20 is equal to a target value.
