摘要/Abstract

摘要： 针对传统减振器的建模方法不能准确描述具有旁通槽的减振器模型问题，根据流体力学缝隙流动、管嘴流动及并联管路流量计算理论，建立了行程敏感减振器的详细数学模型。采用AMESim和MATLAB/Simulink的接口技术对模型进行仿真研究，仿真结果与试验结果符合较好，证明利用AMESim和Simulink对行程敏感减振器建立的联合仿真模型正确可靠。同时，用该模型分析了旁通槽结构参数对减振器性能的影响及敏感程度，为行程敏感减振器的设计和性能预测提供一定的技术支持。

Abstract: For the question of the traditional shock absorber model can’t accurately describe the shock absorber model with the bypass groove, the detailed mathematical model of a stroke-sensitive shock absorber is established by using the hydrodynamics gap flow, nozzle flow and parallel pipe flow calculating theory. The interface technology of AMESim and MATLAB/Simulink is used to simulate the stroke-sensitive shock absorber model, and the calculated results agree well with the test results, which proves that the co-simulation model of AMESim and Simulink is correct, reliable. In particular, the influence rule and sensitivity degree of the shock absorber on the bypass groove structure parameter are analyzed by the model, and the obtained results provide technical support to the design and performance prediction of the stroke-sensitive shock absorber to a certain degree.

Key words: mechanical design, AMESim, Simulink, stroke-sensitive, shock absorber, co-simulation
