Abstract This paper is focused on the isolation property analysis on the HXN3 diesel locomotive cab isolation system for solving the cab excessive vibration problem. An experiment was conducted to investigate the vibration of the HXN3 diesel locomotive. A multi-dimension cab isolation kinetic model was established with considering the cab flexibility, and the vibration frequency response functions were calculated. This paper analyzes the isolation property of the cab isolation system under the high-frequency excited vibration.
