Structure Optimization Design Of Oil Pipe Winding Machine Based On ANSYS

There was a pressing need to improve the pipeline anti-corrosion technology due to the flourishing pipeline transportation, and the winding and protective equipment for oil pipelines thus emerged against that background. The winding and protective equipment for oil pipelines of enterprise horizontal projects were designated as an object of the study with estimated 50 kilograms in gross weight. The model machine for studying was 80 kilograms. To meet requirements of weight reduction, the author optimized the structure of the right support plate and the connector of the winding machine. And through Finite Element Analysis(FEA) and experiment methods, the author performed a detailed theoretical analysis and experimental test for the plate and the connector. Then he got the corresponding stress distributions, deformation, natural frequency and modal shape and optimized their structures according to those results.The paper mainly focuses on the following aspects:(1) Functionally, the winding machine was divided into modules. The working performance of the winding machine hinges on its running module and winding module. While the right support plate and the connector are the vital spare parts to link the two modules. Thus the author made the optimal design for the plate and the connector.(2) The author acquired the size of parts by 2D CAD drawings, constructing the 3D models of the right support plate and the connector in Pro/ENGINEER Wildfire 4.0 Preproduction Software. Then he calculated them in bearing force situation and uploaded the stress in FEA after the plate and connector being led into ANSYS. The final step was to observe the force condition under the static load and to find out the stress distributions and maximum deformation of them.(3) According to the experimental data and results from FEA, the author optimized the structure of the right support plate and the connector, thus to perfect their stress distributions, strengthen the stiffness of the plate, reduce their vibration and deformation, and improve natural frequencies on the on hand, as well as to decrease their sizes and weights and save the economic costs on the other hand.
