| Abstract: |
| The blasting pressure, axial deformation and radial deformation of the steel wire winding hydraulic hose are closely related to the winding angle,and the current research and engineering practice are mainly based on the theory and empirical formula of pressure vessel thin film stress for the four layer arrangement angle hose.?Hower,the assumption of thin film theory is based on the assumption of small deformation and the isotropic material,but the coupling effect will occur while each layer of steel interact under pressur.In the engineering, it has been found that the thin film stress theory for design of the four layers hose in the same winding angle can not be satisfied for the purpose of the optimization any more, whether in the force or the axial displacement.Thus,this paper uses the finite element analysis method to optimize the arrangement angle of four layer winging hose independent,and found that the change of the angle of each layer of the four layers of steel wire winding hose affected stress distribution of the other three layers.Using this rule,we could realize the optimization of hose winding wire arrangement angle, and make the blasting pressure and deformation to meet the requirements of the design purpose at the same time.The results of this paper are proved to have a good correlation with the experimental results. |
