The Lightweight Design And Reliability Study On Efficient High-Speed Automation Equipment Of The Heavy-Load Grinding Feed Unit In Pressure Vessel Of Nuclear Power

Such as nuclear reactor pressure vessels,evaporators,voltage regulators nuclear power equipment manufacturing process involves root-welding,bars-welding and so on key grinding processes, Chongqing Samhaida Co., Ltd. and Chongqing University and CMSP assume the 863 Program " the intelligent and efficient grinding equipment of pressure vessel of nuclear power " and its grinding machines were designed on the demand in accordance with the grinding parameters on the social need, in order to improve the efficiency of processing equipment and processing quality, not only need to do the stress analysis and optimization of beam so to reduce the beam's own weight for its significant parts, increase its structural rigidity and to reduce the bending deformation, but also need to the relevant analysis of active and passive response in order to Improve the dynamic characteristics of beams; through this way, the engineers and technicians can find the most reasonable solution in a complex mathematical models and a large number of parameters and make the machine to be the best optimization mechanical bodies.The rapid development of the finite element method has become an important method of calculation of the project with modern computer technology; It has been widely used in the engineering design and research. This article will introduce the finite element method in topology optimization of beams and equipment work, To achieve the theoretical design process analysis of the beams'light and reliability analysis with the software such as MSC.Fatigue and ANSYS. The main research contents are as follows:â‘ the establishment the three-dimensional geometric model of nuclear power equipment and high-pressure grinding container beams with the Pro / E softwareâ‘¡The simplification of the beams to meet the analysis and the beams in different conditions for the mechanical analysisâ‘¢According to the beams in different stress conditions, the topology optimization analysis is processed. Then the static analysis and dynamic analysis is underway based on the models, Beams are given to optimize the overall design to meet the needs of high-speed feed unit feeding.â‘£Analysis the beam components fatigue life use of fatigue-related theory, provide the referenced documents and suggestion for the product design and equipment maintenance...
