摘要

摘要: 为从某新型载货车的三种驾驶室悬置参数水平值中找出最佳匹配值,进行样车道路试验;应用多体动力学软件建立驾驶室悬置系统虚拟样机模型,通过对比驾驶室悬置系统振动加速度功率谱密度曲线验证仿真模型的可信性。最后以减小驾驶室地板加速度功率谱密度的均方根值为目标,以悬置系统螺旋弹簧刚度、减振器阻尼为因子,运用试验设计技术对驾驶室悬置参数进行优化,改善了驾驶室悬置隔振性能,找出了适合该车型的最佳参数匹配值。

Abstract: In order to find the best parameters from three cab suspension programs, a multi-body dynamics model was built for the cab suspension system of a new designed truck in the multi-body dynamics software ADAMS and verified by the sample vehicle road test through vibration's acceleration Power Spectral Density curve. Taking to reduce the cab floor's vertical acceleration Root Mean Square value as the target, taking the stiffness and the damp of the cab suspension as test factors, the parameters of the cab suspension system were optimized by means of the design of experiments technique. Finally the vehicle's comfort was improved, and the paper provided optimal parameter matching values for the truck to improve cab suspension system performance.
