摘　　要：基于ABAQUS有限元分析软件,建立Φ152mm 4层钢丝缠绕胶管的有限元模型,得到5MPa内压作用下管体的最大轴向伸长率和最大应变能密度,利用正交设计对胶管由内到外1~4层钢丝缠绕角度进行优化,找出最佳角度排列。结果表明:正交设计优化后胶管的最佳角度排列为40°,-35°,25°,-15°,与原设计胶管相比,最大轴向伸长率减小52.08%且成功控制在0.3%以内,最大应变能密度仅增加2.5%,胶管的轴向伸长和使用寿命得到协调控制。This article was based on the finite element analysis software ABAQUS,establishedΦ152mm four layers finite element model of steel wire winding hose,obtained the maximum axial elongation and maximum strain energy density of the tube under the action of 5MPa internal pressure,optimized the winding angle of 1—4layers of steel wire by using orthogonal design,found out the best angle arrangement.The results show that the optimal angle arrangement after orthogonal design optimization of the hose is 40°,-35°,25°and-15°,compared with the original design of the hose,the maximum axial elongation decrease by 52.08%and is controlled within 0.3%successfully,the maximum strain energy density increase by only 2.5%.The axial elongation and service life of the hose are controlled harmoniously.
