全液压转向器作为铰接式工程车辆转向系统的核心部件,对工程车辆的转向性能以及驾驶员的劳动强度有着至关重要的影响.在全液压转向器的实际使用过程中,会产生噪声和振动.采用多物理场协同CAE仿真环境ANSYSWorkbench Environment(AWE),从流场的角度去分析油液在转向器内部的运动情况,得到转向器内部的流场分布,将其中的压力分布作为载荷添加至转向器的阀套与阀芯,通过流固耦合分析,找出结构上的薄弱环节,为转向器内部的结构优化提供依据.%The full hydraulic power steering unit is a key part in the steering system of articulated construction vehicles,which is important to not only the steering performance of the articulated construction vehicles but also the labor intensity of the driver. In practice use, the steering unit has noise and vibration. Through the collaborative multi-physics CAE software-ANSYS Workbench Environment(AWE) and from the fluid flow view,the movement of the oil in the unit is analyzed and the internal pressure distributions is obtained. Then the pressure distributions is added to the valve set and spool of the steering unit as load. Through the fluid-structure interaction analysis, the weak point in the structure is found, that provides the basis of the optimization of the internal of the steering unit.
