摘　　要：针对钢丝缠绕高压软管结构在长度方向具有周期性变化的特点,采用ANSYS软件的参数化建模技术,使用梁单元BEAM188和体单元SOLID186分别对软管的钢丝增强层和橡胶层进行单元划分,采用线接触单元CONTA176和目标单元TARGE170分别模拟软管增强层中不同钢丝层之间的连接关系,并以此为基础建立了软管长度方向代表性体积单元(RVE)细观力学有限元模型。利用该模型求解出软管爆破失效时的应力和位移分布云图,使用软件的参数扫描技术分析了钢丝缠绕角度的变化对软管钢丝层最大应力的影响规律,按照第一强度理论的失效准则对软管的爆破压力进行了数值计算预报,并通过试验验证了软管有限元模型计算结果的精度。最后,基于ANSYS软件的多目标优化设计模块,采用响应曲面算法对软管各层钢丝缠绕角度等结构参数进行了优化设计,优化后的软管爆破压力与初始结构的爆破压力相比提高16.33%。In view of the structure of steel wire wound hydraulic hose with periodic changes in the length direction,this paper adopts parametric modeling technology of ANSYS software,and uses beam element BEAM188 and body element SOLID186 respectively to divide the steel wire skeleton layer and rubber inner layer of the hose.At the same time,CONTA176 and TARGE170 are used to simulate the connection relationship between different steel wire layers in the hose skeleton layer,and on this basis,the meso-mechanical finite element model of representative volume element(RVE)in the hose length direction is established.According to the principle of the first strength theory,the maximum bursting pressure of the hose is predicted by the parametric finite element model of the hose RVE,analyzed the mechanism of hose explosion failure and the accuracy of the finite element model is verified by experiments.Finally,based on the optimization design module of ANSYS software,the influence of the winding angle of the steel wire on the maximum tensile force of the hose steel wire layer is studied by using the parameter scanning technology.The zero order optimization algorithm is used to optimize the winding angle of the steel wire in each layer of the hose.The bursting pressure of the hose after optimization is 16.33%higher than that of the initial structure.
