Abstract

The invention discloses a structural parameter optimizing design method of a nonlinear snake-shape resisting damper. With a fluid mechanic principle of an internal structure of the snake-shape resisting damper, a nonlinear hydraulic model is built, the nonlinear hydraulic model and a vehicle dynamic model are combined into a joint simulation model, the joint simulation model is used for analyzingthe influence of internal structural parameters of the snake-shape resisting damper to vehicle stability, and therefore optimizing design of structural parameters of the snake-shape resisting damper is achieved. By means of the structural parameter optimizing design method for resisting the nonlinear snake-shape resisting damper, the model is simplified, the reasonability of parameter selection isimproved, and the efficiency during simulation is improved, so that obtained parameters are better optimized.

Description

Technical field [0001] The invention relates to the technical field of vibration damping devices, in particular to a non-linear anti-snake-shaped vibration absorber structure parameter optimization design method. Background technique [0002] At present, the current operating speed of high-speed railway vehicles has reached 350km / h, but this will also make the operating conditions worse than at low speeds, and the vibration and shock will also be greater. In order to obtain higher speeds while ensuring vehicle dynamics, many new technologies are applied to high-speed railways, such as lightweight vehicle technology, high smoothness and high stability ballastless tracks. The application of these technologies will lead to changes in the working conditions of vehicle suspension components: one is the reduction in the relative displacement amplitude between the suspension component and the vehicle; the other is the increase in the relative movement frequency between the suspension co...
