Oil-free scroll vacuum pump with its high cleanliness, smooth operation, energy saving, small size, light weight, low noise characteristics, once launched on a wide range of applications. However, due to technical problems in the development, design, manufacturing process, yet large-scale factory production. Oil-free scroll vacuum pump to fill the gaps developed in accordance with the requirements of the Chinese market has become an important task of the domestic science and technology workers. This article is the actual development of the project, combined with oil-free scroll vacuum pump oil-free scroll vacuum pump parametric 3D solid model, the parametric model the finite element analysis. Repair of oil-free scroll vacuum pump parametric modeling, model, parametric load applied and move, given the scroll body temperature field and other issues more in-depth research. In this paper, the finite element analysis software ANSYS actual physical model of oil-free scroll vacuum pump, the orbiting scroll, set the temperature field, stress field and the resultant thermal deformation of the scrolls were simulated and research. UG software established oil-free scroll vacuum pump, three-dimensional solid model of the fixed scroll, the material properties of the parts are included in the model, the model can be activated in any direction to observe and feel free to change the size of change for evaluation. In order to optimize the dynamic, the purpose of the fixed scroll geometry, ANSYS software is used to analyze the temperature, stress and thermal deformation, and the results verify the oil-free scroll vacuum pump orbiting scroll and fixed scroll design reasonable , oil-free scroll vacuum pump design help. In this paper, GRIP UG secondary development language to create a three-dimensional parameter-driven model of oil-free scroll vacuum pump. Enter the main modeling parameters automatically create a three-dimensional model of the optimal parameters of oil-free scroll vacuum pump, manually modify the generated model allows UG, oil-free scroll vacuum pump design automation, improved design accuracy and efficiency. Using APDL programming language command, you can achieve the parametric modeling, parameterized mesh and control, material parameters defined load parameters and boundary conditions defined macro organization and management of finite element analysis. This paper uses finite element analysis software ANSYS secondary development language APDL and UIDL programming eventually reach the actual physical model of oil-free scroll vacuum pump. Control of the parameters of the equation of the movable scroll is based on the variables of time and space heat load loaded state. Also relates to the production of heat load equation calculation process and a good user interface. This article will be based on ANSYS parametric design will help. Achieve communication between UG and ANSYS software, the successful implementation of the model repair, transmission and processing, so that the imported model in ANSYS environment can smoothly meshing, loading operations and further work. In this way, the UG and ANSYS organically combine these two large-scale software, intended to complement the limitations of ANSYS software for complex three-dimensional solid model, finite element analysis of engineering problems in the process and results more streamlined and accurate .
