摘要: 首先建立了筒式液阻减振器阀片受力变形的精确有限元模型,求出了阀片所受载荷与阀片挠度曲线的数值关系,从而得到了减振器内部阀系流量与压差的关系。然后将此阀系的特性曲线代入到基于结构的减振器模型中,并把减振器模型的输出曲线与台架示功试验曲线进行对比。仿真结果与试验结果有很好的一致性,验证了该模型的准确性。最后,通过仿真研究了复原阀结构参数对阻尼特性的影响。

Abstract: A twin-tube hydraulic shock absorber F-V model is proposed based on structure parameters. First, a finite element model of the shock absorber rebound valve plate is established, and the load versus valve deflection curve is obtained with the model. The relationship between flow rate and pressure variation is then calculated. Then, this curve is integrated into the shock absorber model. The comparison between the model output and experiment data demonstrates the high accuracy of the proposed model. Finally the influence of the structure parameters of the rebound valve on the damping performance is analyzed through simulation.

Key words: vehicle engineering, valve plate deflection, finite element method(FEM) modeling, shock absorber
