Process to determine mechanical parameters for a reduced three mass model of a branched cardan hollow shaft traction drive for locomotives identifies proper frequencies

摘要

A process to find mechanical parameters (J,c) of a reduced three-mass model of a branched Cardan hollow shaft traction drive train comprises identifying its proper frequencies (omega ) depending on the angular velocity and calculating the mechanical parameters using these, the vector elements (phi ) of the proper frequency and the predetermined total moment. An independent claim is also included for a device for the above process.
