The Simulation of Coupling Problem of Initiative Control of Suspension in Articulated Vehicle

提出了轮式铰接车辆悬架主动控制中转弯时的动力学耦合模型,从耦合模型和仿真模型证明了轮式铰接车辆悬架三维方向存在耦合问题.同时从提高铰接车辆行驶速度评价,说明存在利用耦合效应进行悬架主动控制策略设计、构建通过悬架的单向作动控制策略、探讨最大限度减低三维方向车辆振动的可能性,即通过悬架单方向实时主动控制,达到抑制其他方向振动的目的.为轮式铰接车辆悬架实施主动控制的方法与策略提供了理论依据和方向.

This paper put forward the dynamic coupling model of articulated vehicle when its running coupled with turning around, and gave the concrete form of this coupling model to prove the existing coupling problem of single suspension when putting in an additional load in its three-axle directions, meanwhile using the simulation method to prove the probability of reducing the vibration in its three axles through constituting the strategy of single-directional control in the suspension. It will provide certain theoretical basis for the initiative control of suspension in the articulated vehicle as a final goal.
