| 摘 要： | 提出了一种适用于半挂汽车等铰接车辆的动态垂直载荷转移量算法,该算法考虑了鞍座等相关因素对半挂汽车车轮垂直载荷转移量的影响。基于九自由度半挂汽车动力学模型,对转角输入条件下半挂汽车动态垂直载荷变化进行了系统的分析,并利用实用化半挂汽车动态仿真平台TruckSim对相关模型进行了对比验证。研究结果表明,该算法能更加准确地分析半挂汽车垂直载荷变化,对车轮垂直载荷转移量的估计值可提高约10%,从而解决了传统算法在适应性和准确性上不足的问题。

| Abstract: | Considering the influence of related factors such as saddle,an improved algorithm to estimate dynamic vertical load transfer for tractor-semitrailer was proposed.Bases on dynamics model with 9-DOF vehicles,the vertical load transfer with steering input was analyzed and the related models were verified by a practical simulation platform for tractor-semitrailer,TruckSim.The results show that the improved algorithm is more accurate to analyze the change of wheels' vertical load and the estimated value of verti... |
