摘要
在ADAMS/car下建立重型半挂车模型,并选取双移线这一典型工况,在不同附着系数路面上对极限工况下重型半挂车在不同车速时的侧翻、折叠和挂车摆振问题进行了稳定机理分析。结果表明,重型半挂车辆在附着系数较高的良好路面上容易发生侧倾失稳,而在附着系数较低的湿滑路面上则更容易发生横摆和折叠失稳。提出了相应的改进措施。
The heavy-duty semi-trailer model was set up in ADAMS/car,and based on the typical condition of double lane change,the problems of the rollover,jackknife and trailer swing under extreme conditions at different speeds on different roads with different friction-coefficient were analyzed.The results show that the vehicle tends to rollover on the high friction-coefficient road, while the vehicle tends to yaw and jackknife on the low friction-coefficient road.The paper also put forward some improved measures to solve the above problems.
