Abstract

The invention relates to an analytic calculation method for the optimal damping ratio of seat suspension of a high-speed rail vehicle, and belongs to the technical field of suspension of high-speed rail vehicles. As a 1 / 4 vehicle body-seat traveling vertical vibration model of the rail vehicle is set up, an objective function of the optimal damping ratio of seat suspension is set up by means of the random vibration theory and analytically calculated to obtain the optimal damping ratio of seat suspension. It can be known through design examples and SIMPACK simulation verification that the optimal damping ratio of seat suspension can be obtained accurately and reliably through the method, and a reliable design method is provided for designing the optimal damping ratio of seat suspension of the high-speed rail vehicle. By means of the method, the design level and product quality of a high-speed rail vehicle suspension system can be improved, riding comfort of the vehicle is improved, product design and test cost can be reduced, the product design cycle is shortened, and the international market competitiveness of the rail vehicles in China is enhanced.

Description

technical field

[0001] The invention relates to a high-speed rail vehicle mount, in particular to an analytical calculation method for the optimal damping ratio of a high-speed rail vehicle seat mount. Background technique

[0002] The damping ratio of the seat suspension system has an important influence on the ride comfort of high-speed rail vehicles, and its design or selection is an important parameter based on the design of the seat suspension system shock absorber valve system parameters. However, according to the available information, since the rail vehicle is a multi-degree-of-freedom vibration system, it is very difficult to analyze and calculate its dynamics. At present, there has been no systematic analysis of the design of the optimal damping ratio of the seat suspension at home and abroad. Most of the calculation methods are based on computer technology, using multi-body dynamics simulation software SIMPACK or ADAMS / Rail to optimize and determine its size throu...
