基于虚拟样机的某型轻卡平顺性仿真分析

Simulation Analyses on Light-duty Truck Ride Comfort Based on Virtual Prototype

以某型轻卡为研究对象,利用虚拟样机技术建立整车模型。在B级路面下,以不同车速进行了行驶平顺性仿真分析评价。结果表明:平顺性在很大程度上受到汽车行驶速度的影响。最后根据分析结果,提出模型优化的合理建议,为轻卡舒适性研究提供参考。

It takes a new-type light-dUty truck as study object, vehicle model was built with virtual prototype technology. Vehicle ride comfort simulation analysis was made with different speeds in the case of B-road. The result showed that speed has a large of influences on the ride comfort. Finally, some reasonable recommendations were provided for optimization of vehicle model, and also some references were provided to light-duty truck ride comfort according to the result.
