摘要
介绍了一种空气弹簧力与减振器阻尼力具有耦合关系的新型悬架减振支柱的结构设计方案、工作原理、阻尼调节和空气弹簧气室容积调节方法,建立了新型减振支柱气、液力耦合动力学模型。设计了某乘用车前悬架的新型减振支柱,通过仿真计算分析了该减振支柱的非线性动力学性能、主要影响因素及气液力耦合作用关系。台架试验表明,新型减振支柱作用力的仿真结果与试验结果接近,验证了新型减振支柱设计方案的可行性和气液力耦合动力学模型的正确性。
Structure,basic working principle,method of damping adjusting and air-chamber volume adjusting for a new type suspension strut consisted of the air spring and the hydraulic shock absorber are introduced in this paper.A gas-liquid coupling dynamic model for the new type suspension strut was established.New front suspension strut of a passenger car was designed,the nonlinear dynamics performance of the strut,main influence factors and gas-liquid mechanical coupling relationship were analyzed by using simulation software.Bench test results indicate that testing results were very close to the simulation results,verifying that the design scheme of the new type suspension strut is feasible and the established gas-liquid coupled model is correct.
