新型全地形车操纵稳定性评价分析

Evaluation of New All-terrain Vehicle Handling Stability

以某四轮全地形车的实车模型为基础,设计新型三轮全地形车。基于Adams建立全地形车动力学模型,借鉴汽车操纵稳定性试验方法,对该新型全地形车进行稳态回转、角阶跃输入和蛇行试验操纵稳定性仿真和评价。结果表明:新型全地形车总评分为77.9,原型全地形车总评分为75.4;新型全地形车在以上3种试验中操纵稳定性均优于原型全地形车。

A new model of three wheel of all terrain vehicles（ATV） is designed based on the modifi- cation of an old model of all terrain vehicles. Then using the software ADAMS, we build a multi-body- dynamics model of all terrain vehicles, and d cedure for automobiles for analyzing handling procedures for automobiles, steady static circ raw lessons from the controllability and stability test pro- stability based on the controllability and stability testing ular simulation, steering wheel angle step input simula- tion and snake steer roll simulation and evaluation. The results show that the new ATV＇ s total score is 77.9 or in while the prototype ATV＇ s total score is 75.4. The new ATV in the above three tests is superi- handling stability to the prototype ATV
