Simulation Analysis of Cylinder Winding Prestress Based on Ansys

Abstract

Abstract Based on the distribution and layer characteristics of the prestressed steel wire-wound cylinder of the four-column hydraulic press, its supporting parts not only bear the constant stress caused by internal pressure, but also withstand the alternating stress caused by the steel wire-wound cylinder, and then produce gradual accumulation of plastic deformation. This paper uses theoretical calculation formulas to solve the corresponding parameters, establish a three-dimensional constitutive model, uses Ansys workbench to optimize its thermo-solid coupling simulation, and compares with the theoretical calculation results to verify the rationality of the design of the prestressed winding cylinder with cooling loading. The design of prestressed steel wire winding cylinder of 400MN plate hydraulic press is combined. Setting cylinder rated working pressure of 88MPa,an inner diameter of 1500mm,its wire winding layers are divided into 10,8,6,4 and 2.Based on the comprehensive analysis of the simulation results, the optimum initial stress table number of steel wire winding is obtained. According to the optimum initial stress table number, the influence law of preload coefficient on the design parameters of prestressed steel wire winding cylinder block is analyzed.
