摘要
现行车辆悬挂与转向系统的调校大部分都是利用在ADAMS/Car模块里面存有的数模分别进行轮跳和转向的仿真和调校。这种方法往往顾此失彼,调整轮跳参数的同时也修改了已经调整好的转向参数(反之亦然)。这使得需要多工况反复仿真和调校,需要多次进入后处理查看结果参数,在Car模块里面难以实现同时调校和直观的查看调校结果。鉴于上述问题,在ADAMS/View模块里面建立了轮跳与转向复合模型,创建了顺序驱动与多种测量函数,进行了多种工况联合仿真和调校,在仿真界面直观的观察硬点修改后对各项参数的影响,从而快速对悬架参数进行调整优化,减小轮跳过程中轮胎角度的变化量,缩减了轮胎侧向滑移量,并且优化了转向阿克曼角,达到了快速、便捷、直观地优化前悬挂动力学性能的目的。
Most of the adjustments of the current vehicle suspension and steering system are based on the simulation and adjustment of wheel jump and steering using the digital and analog stored in the ADAMS/Car module.This method tends to lose sight of each other,when adjusting the wheel jump parameters while modifying the already adjusted steering parameters(and vice versa).This makes it necessary to repeatedly simulate and adjust under multiple operating conditions,and enter the post-processing to view the result parameters multiple times.It is difficult to achieve simultaneous adjustment and intuitive viewing of the adjustment results in the Car module.In view of the above problems,a compound model of wheel jump and steering has been established in the ADAMS/View module,a sequence drive and multiple measurement functions has been created,the joint simulation and adjustment of various working conditions has been conducted,and the influence of hard points changes to each parameter has been observed intuitively in the simulation view.Therefore,the suspension parameters can be quickly adjusted and optimized to reduce the change of the tire angle during the wheel jump,reduce the amount of tire lateral slip,and optimize the steering Ackerman angle.It achieves the purpose of optimizing the dynamic performance of the front suspension quickly,conveniently and intuitively.
