Structural Analysis And Optimize Design Of XSP800 Take-up And Traverse Machine

Research on the take-up and traverse machine mostly concentrated in developing of new products and control system,but rarely involved in structural analysis and structural optimization and mechanical test. at present, on the design of the take-up and traverse machine structure theoretical basis for the lack of effective, mostly follows the usual design philosophy, the conventional methods, was carried out in an analogy way from experience. Often the safety factor is too large assigned, and inevitably result in the design of the structure is too large in size and weight, Structure design is not quite reasonable. The gantry type traversing machine is one of the main structure, therefore XSP800 take-up and traverse machine structural analysis and optimal design has important practical value.In this paper, based on finite element theory, using ANSYS finite element software to, completed the structural of the XSP800 take-up and traverse machine for analysis and optimization design. According to actual situation, the traverse machine separate into two parts: frame structure and the lifting structure, to carry out structural analysis and optimization.Firstly, using ANSYS software to analyze the frame structure, analyze the forces and calculate the loads on the frame, by build a finite element model of the frame in ANSYS, in the three operating conditions, checking the structure of the frame strength and stiffness, verify the reasonableness of the original design. Performance to be improved frame structure strength. Completed modal analysis of the structure, obtained natural frequencies and mode shapes of the frame structure. Completed the fatigue life of the frame structure, obtained dangerous parts fatigue life of the frame structure.Secondly, using ANSYS software to analyze the structure of lifting system. By build a finite element model of the lifting system in ANSYS, imposed boundary conditions and solving the equation, the stress and displacement distribution is found, and checking structural strength and stiffness, verify the security of the original design, as a basis for further structural optimization.Thirdly,do the stress-test experiment in the workshop. Stress curves of the test point are gained by DH-5920, a dynamic signal test and analysis system, under a certain working condition. Comparing and analyzing the experiment results and the simulation results can get such a conclusion that the simulation results are correct.Finally, structural improvement and optimization of the XSP800 take-up and traverse machine are carried out. Using ANSYS optimization design module to the frame and lift system to optimize the design. The optimal design in strength and stiffness properties were improved than the original design. Weight also has obvious reduced, reached the goal of optimal design. This scheme can be regarded as a reference for the XSP800 take-up and traverse machine design, the design of other similar institutions can also referenced.
