某高端载货汽车的操纵稳定性能仿真分析与调校

Simulation Analysis and Adjustment of Handling Stability for A High-end Truck

针对某新开发的载货汽车试制样车操纵稳定性能指标低于设计目标问题,应用ADAMS软件建立了其动力学模型,对其操纵稳定性能进行仿真分析。结合主观评价试验,建立了参数化板簧模型,利用相关性分析技术对板簧弧高等参数进行调校。试验结果表明,调校后该车操纵稳定性能指标有较大提升,达到了高端载货汽车的设计要求。

Handling stability of a newly developed truck prototype is inferior to the design objective, to solve this problem, we build the dynamics model using ADAMS software and simulate its handling stability. According to the results of subjective evaluation test, we establish a parameterized leaf spring model, and use correlation analysis technology to adjust the leaf arc height and other parameters. Test result shows that, after adjustment, the handling stability of this truck is improved significantly and meets the design requirements.
