Nonlinear Characteristics of Gear Transmission Systems of Locomotive Excited by Torque Fluctuation of Traction Motors
摘要
Abstract
Considering the external and internal excitations such as torque changes of traction motors, load torque fluctuations caused by stick-slip vibrations of wheel/rail,backlashes,time-varying mesh stiffness and transmission errors,a centralized mass model of the spur gear drive system was established for a typical locomotive HXD. The system responses were calculated by numerical methods combining with the bifurcation diagrams,phase plane portraits,Poincaré maps,displacement time curves and spectrograms. The influence law of torque changes of traction motors on the nonlinear system was also analyzed. The research results reveal a complex nonlinear dynamic evolution mechanism comprising one-periodic responses, multi-periodic responses and chaotic responses.关键词
