[Abstract]:The dynamic magnetic linear compressor has the advantages of compact structure, small volume, large power and high efficiency. However, the compressor has high technical requirements and high design difficulty. Numerical simulation of the key components of the compressor requires strong application ability of large-scale professional software and practical engineering experience, which often leads to low design efficiency. At present, no special design software has been developed for linear dynamic magnetic compressor at home and abroad. How to combine the design experience, typical structure, calculation method and material data accumulated by the enterprise or industry with the advanced computer software secondary development technology, so as to improve the design efficiency significantly, It is one of the main problems in the field of linear compressor research. In this paper, a special software simulation platform for the key components of the moving magnetic linear compressor is designed and developed, which is based on the specific requirements of the actual project and combined with the large-scale professional software such as Pro/E,ANSYS, Ansoft and Fluent. The method can also be applied to the design of other similar compressors after proper adjustment and expansion, and has significant engineering application value. This paper mainly includes: 1. The overall design scheme of the simulation platform for the key components of the moving magnetic linear compressor. According to the general engineering requirements of the compressor design, the overall goal of the simulation platform is put forward through the analysis of the simulation platform. According to the characteristics of linear motor, flexible plate spring and gas bearing, and the actual functions of domestic and foreign software, the suitable supporting software is selected to develop the simulation platform in the light of the characteristics of linear motor, flexible plate spring and gas bearing, which are the key components of the dynamic magnetic linear compressor. On this basis, the integrated design scheme of the simulation platform is put forward, and the feasibility of the simulation platform is analyzed from the aspects of technical feasibility, operational feasibility and economic feasibility, and the necessity and feasibility of the platform are pointed out. 2. Design of Simulation platform for key components of dynamic Magnetic Linear Compressor using VS2008 and Qt to design the main interface of the simulation platform for key components of dynamic Magnetic Linear Compressor to indicate the simulation and analysis inlet of each key component. The second development of Pro/e is carried out by using Pro/Tookit secondary development kit, and the parametric modeling of Redlich linear motor model is realized. Based on the theory of material mechanics and finite element method, the second development of ANSYS is carried out by using UIDL and APDL, and the parametric analysis of flexible plate spring parts is realized. Based on the basic theory of electromagnetic field and finite element method, the second development of static and dynamic analysis of linear motor is realized by using the macro command function of Ansoft. Based on the theoretical basis and numerical model of computational fluid dynamics (CFD), the second development of Fluent is carried out by using Jounal file, and the parametric analysis of gas bearing is realized. Finally, by writing the corresponding code to realize the data sharing and communication between the various software, the dynamic magnetic linear compressor simulation platform is developed and realized, and the simulation platform is used. The designer can realize the analysis and design of many linear compressors with similar structure only by inputting parameters in the special dialog box. 3. The software simulation platform engineering examples are preliminarily verified by three engineering examples: linear motor, plate spring and gas bearing, which are the key components of the dynamic magnetic linear compressor. The correctness and practicability of the simulation platform for the key components of the moving magnetic linear compressor are preliminarily verified. Compared with the traditional simulation process, this simulation platform has obvious advantages in shortening the simulation period.
