摘要
阐述HTF5980A底盘油气悬架的结构、工作原理,基于Amesim平台,详细讨论油气悬架各个部位的建模方法,建立其仿真模型,计算连通式油气悬架的动态特性,并与台架试验结果进行对比。试验结果表明:所建立的模型能够正确描述连通式油气悬架的动态特性。基于Adams平台建立HTF5980A整车动力学模型,基于Amesim建立整车悬架系统液压部分模型,完成整车平顺性联合仿真。研究结果不仅为连通式油气悬架优化设计提供了依据,而且为整车动力学及疲劳分析奠定了基础。
The structure and working principle of the connected Hydro-pneumatic suspension for HTF5980A chassis were presented.And then,an Amesim model of the connected hydro-pneumatic suspension for multi-axle vehicle was built,a method on modeling the hydro-pneumatic suspension was discussed.The dynamic characteristic of it was studied by simulation,and the result was compared with the result from bench test.It was indicated that the Amesim model could exactly describe the connected Hydro-pneumatic suspension system.The Adams model of the HTF5980A chassis and the Amesim model of the whole vehicle suspension system were established,the ride comfort was studied by co-simulation.The result provided a basis for both the optimal design of connected hydro-pneumatic suspension and the dynamic analysis of vehicle system.
