基于ADAMS车辆随机振动的模拟仿真研究

Simulation and analysis of Vehicle under random vibration input

论文以某轿车为研究对象,基于机械系统动力学仿真软件ADAMS/CAR建立包括前后悬架子系统、转向子系统和前后轮胎子系统的车辆整车模型。运用ADAMS/CAR路面建模器建立B级随机路面模型,通过ADAMS/CAR/Ride对整车模型在所建立的随机路面上进行模拟仿真研究,以底盘的加权加速加速度均方根为评价指标,对其进行平顺性评价。

This paper takes a car as the research object.The multi-body dynamic model of a commercial vehicle is established in which suspensions tires and the vehicle body the steering system are considered.Through the road-builder of the software ADAMS/CAR establish the B random vibration ride and simulation the model through the ADAMS/CAR/Ride in this B random vibration road.Based on the weighted acceleration root mean square value of the chassis,the ride comfort evaluation is carried out.
