摘要：
With the continuous improvement of locomotive speed, it has demanded higher requirement of the stability and operating safety. Firstly, taking into account the composite factors such as bear elastic-support and gear mesh stiffness. the dynamical model of Locomotive transmission Finite-element system is established based on Lagrange principle of minimum potential energy. Secondly, numerical solution of critical speed and modal response solved by iteration method. Finally, under the action of bear supporting stiffness, gear mesh stiffness and wheel-rail contact force, the amplitude-frequency response of rotor system are analysed qualitatively. The results show that when frequency was near to the gear mash frequency and natural frequency of the drive system, vibration amplitudes increased obviously with complex environment. In the meantime, the amplitude of the passing frequency of rolling bearing decreased. Moreover, under influence of the rail contact stiffness, vibration amplitude of associated with the gear mesh frequency, natural frequency and passing frequency of rolling bearing were disturbed. © 2018 Journal of Mechanical Engineering.
