基于TruckSim的商用车操稳性能验证

为了在产品开发前端有效评估设计样车性能,识别性能风险点,提升产品开发效率,利用多体动力学软件TruckSim进行商用车操稳性能建模、仿真验证。首先遵循整车-子系统-零部件逐级建模思维分别完成整车、车身、转向、悬架、轮胎、动力总成、制动系统等模型建立,在此基础上,基于GB 6323试验方法对其进行稳态回转、低速回正、蛇形绕桩等性能仿真。仿真结果表明:所开发的样机操稳性能能够满足项目既定指标要求,为产品开发提供了依据。

The Handling Stability Performance Verification of Commercial Truck Based on the TruckSim Software

In order to effectively evaluate the performance of the design prototype,and identify performance risk point at the front of product development,improve product development efficiency as well.Use the multi-body dynamics software TruckSim to model and simulate the handling stability of commercial vehicles.First,following the vehicle-subsystemcomponent gradual modeling way to complete the model establishment of the vehicle,body,steering,suspension,tire,powertrain,and braking system.Performance simulations such as steady-state cycle,low-speed return to normal,and serpentine test are carried out,based on the GB 6323 test method.Simulation results show that:The performance of the prototype can meet the project's established index requirements,which provides foundation for the next development works.
