Abstract

During the winding construction, the pre-stressed wire wound orthogonal preload frame bears the preloading force applied by the steel wire from top, bottom, left and right simultaneously. Compared with the ordinary preload frame, it bears complex force, there is no obvious distribution rule on the surface stress field, and it is difficult to monitor the preloading force. The monitoring of preloading force is crucial for the wire wound process and will directly influence the working performance and safety during the manufacturing process of multi-ram die forging hydraulic press. It uses the finite element wire layer temperature drop method to simulate the winding process of pre-stressed wire wound orthogonal preload frame, studies the distribution of surface stress field during the winding process, confirms its unidirectional stress distribution area and key points of stress monitoring and analyzes the overall deformation during its winding process, so as to solve the pre-stressed monitoring problem and overall stiffness analysis during the winding process. The result demonstrates that the finite element computation result of overall deformation of frame substantially agrees with the test result, and it shows the feasibility of simulating the steel wire winding process by temperature drop method. In addition, the result of preloading force measurement based on the sticking scheme established by finite element substantially agrees with the theoretical value of design, and it solves the pre-stressed monitoring problem during the process of winding construction of pre-stressed wire wound frame.
