摘  要:
设计了一种六足并联悬架系统用于拖拉机驾驶室减振,由于悬架系统的几何参数和物理参数难以确定,首先基于拉格朗日方程推导6自由度振动模型,以驾驶室6个方向固有频率和悬架系统阻尼比、解耦度为优化目标,建立多目标优化数学模型,运用灵敏度方法对该系统进行优化设计研究,最后与目前拖拉机橡胶衬垫驾驶室悬置系统进行比较,结果证明其具有良好的减振效果,同时为该悬架系统被动控制参数的选择提供理论依据。

摘  要:
A six-legged parallel suspension system for tractor cab vibration reduction was designed. Aimed to the problems to determine the physical and geometrical parameters of the tractor cab hexapod parallel suspension system,the 6-DOF dynamic model was established based on the Lagrange Equation. Taken the natural frequency of the suspension system,and the damping and decoupling degrees of cab in six direction as optimize target,multi-objective optimization model was established and the sensitivity method was used in the system optimal design research. Compared with the traditional rubber liner suspension system of tractor cab,the results proved that it had good damping effect,and provided a theoretical basis for parameter selection for passive vibration control and the manufacturing of suspension system prototype.
