摘　　要：液压集成块孔系结构复杂,人工设计方法主要取决于设计者的经验,其设计效率低,失误率高,节流损失大。文中提出将三维参数化设计软件Creo与有限元仿真软件Ansys相结合,利用Creo软件构建液压集成块三维实体模型,并进行孔系干涉检查和最小壁厚尺寸检测。利用Ansys Workbench软件中的Static Structural模块和CFX模块完成流道结构静力学和流场特性联合仿真分析。仿真结果表明,孔道相贯刀角容腔处等效应力和压力损失最大,压力损失大小与刀尖角区域长度尺寸有关,设计时应选择最佳尺寸长度,以减小系统压力损失,提高系统能源利用效率,且进行机加工时应尽量减少或避免应力集中。The hydraulic manifold block hole system structure is complex and the manual design method mainly depends on the designer's experience,so its design efficiency is low,the error rate is high and the throttle loss is big.The method of combining Creo with Ansys is proposed in this paper,the 3D solid model of the hydraulic manifold block was built using Creo software,and carried out the interference inspection and the minimum thickness dimension measurement of holes.Static Structural module and CFX module in Ansys Workbench software were used to complete the co-simulation analysis of flow channel structure statics and flow field characteristics.The simulation results show that the equivalent stress and pressure loss are the largest in the cavity of the intersecting knife angle,and the size of the knife angle area has a significant influence on the pressure loss.The optimum size and length should be selected in the design to reduce the pressure loss of the system,improve the energy utilization efficiency of the system,and minimize or avoid stress concentration during machining.
