On the Vibration of a Power-Transmission System Having Angular Clearances, Part 3 : Experiment of a Two-Mass One-Stiffness System Retarded by Collision Damping as well as Velocity-Proportional Damping

Abstract

To examine the approximation of collision damping in the former report, Part 2, here a two-mass one-stiffness system is checked experimentally, and as a result the author verifies that the theory gives practically sufficient accuracy of the order of 1st approximation. The experimental system is made up of an electrical dynamometer, an intermediate shaft, a variable clearance joint, and a fan, excited by a piston crank mechanism. The author reads the torque and r. p. m. at the maximum amplitude state, besides detecting electrically from the revolving system its fluctuating torque, collision velocity and touching of clearance parts.
