汽车前悬架系统部件之间的运动关系十分复杂,对整车的操纵性和平顺性有很大的影响。在现有的汽车双横臂前悬架数据的基础上,用ADAMS软件建立悬架模型,并对模型进行仿真计算,研究分析评价悬架数据的合理性。最后分析对比在该车上采用麦弗逊式独立悬架代替双横臂式独立悬架的优越性。 相似文献

应用ADAMS软件对双横臂独立悬架进行建模。在路面输入、弹簧、减振器一定的情况下,通过改变悬架的主销、上横臂、下横臂在空间的9个几何参数对悬架仿真。仿真研究表明主销长度和主销内倾角是影响车轮侧向滑移关键参数,大内倾角和短主销长度大大降低轮胎的侧向滑移。在汽车稳定性许可范围内,为如何确定悬架参数而提高轮胎寿命提供了理论指导。 相似文献

本文在理论上建立了一套基于主动力反馈原理的新型主动阻尼悬架的设计和优化方法。首先提出了该主动阻尼悬架的实现模型,该模型是在传统的液力减振器的基础上,应用半主动控制的思想,结合力反馈的原理建立起来的内部液压反馈阻尼网络模型。理论优化分析和计算机仿真表明,通过该液阻网络模型,即可以实现电控的主动阻尼悬架的功能,它可以根据汽车行驶路况的好坏,自适应地调节悬架阻尼大小以实现主动阻尼悬架的最优控制。 相似文献

针对国产某微型轿车,在建立汽车悬架系统5自由度模型和时域路面模型基础上,对悬架系统的线性弹簧和非线性阻尼参数进行了优化。根据优化结果,对悬架系统的刚度和阻尼进行了匹配设计。经试验表明:座椅加速度自谱峰值减小7.4%,加速度均方根值减小19.4%,有效地改善了该车的行驶平顺性,证明时域优化方法对于悬架系统非线性参数优化是可行的。 相似文献

In this paper, a load-leveling suspension system with a magnetorheological (MR) damper is investigated. In this suspension system, the MR damper is connected to a spring to form a load-leveling suspension system. The system effective stiffness and damping can be adjusted by controlling the MR damper. The characteristics of a load-leveling suspension system are studied first. When the linear damper is replaced with an MR damper, the averaging method is adopted to obtain the steady-state response of the nonlinear system. A comparison demonstrates that the results of the averaging method are in good agreement with those obtained by numerical simulations. The analytical results are then verified experimentally. The load-leveling suspension system studied here is able to adjust both suspension stiffness and damping and, hence, it may provide more effective vibration control in a wider frequency range, when the damper is controlled. 相似文献
