摘　　要：根据车的参数来创建汽车自由度线性振动模型,在模型里设定后轮滞后路面随机激励,并使用MMALTAB/SMULNK来给车辆的振动采取仿真模拟,把前后悬挂刚度改造成为前后的车身的加速度,并采取科学合理的研究,然后再给悬架刚度采取更新措施,这样一来就能够提高车辆的舒适度,并给车辆平顺设计工作创造出参考指标。According to the parameters of the car to create auto degrees of freedom linear vibration model,the model set the rear lag road random excitation,and use MMALTAB/SMULNK to take simulation for the vibration of the vehicle,the front and rear suspension stiffness transformation become in front and back of the acceleration of the body,and take scientific and reasonable research,then the suspension stiffness updating measures,thus can improve the comfort of the vehicle,and give the vehicle a smooth design work to create the reference index.
