Development And Application Of Program For Strength Calculation Of Volute Case Of Pump

At present, the Computer Aided Design has been developing deeply and vigorously, putting practice into various fields of social production broadly, and lots of CAD software with the strong characteristics of the speciality have been coming forth, In the renovation of CAD, pumps, as a main part of fluid machinery, attain great enhancement from design theory, design means to production.Strength calculation and checking of parts is necessary in the design of pumps. As one of the most important parts of a pump, the design of volute case has great effect on performance and lifespan of complete machines. With CAD put practice into pumps industry extensively, conventional methods of strength checking could hardly meet the demands in design precision and efficiency.Based on this background of technology, this paper tries to develop a program of strength calculation and checking of volute case on the ObjectARX 3.0 and Windows platform using Visual C++ 6.0. This program can improve greatly not only the design efficiency but also the design precision of calculation and checking of volute case.The main research contents of this paper are below:The present situations of pump CAD at home and abroad are summarized, and the existing questions are pointed out. The meanings and basis of the subject are analysed, and the theory of strength calculation and checking of volute case are explored and discussed deeply. The development platform and tools and several key technologies are described and analysed in detail. This paper has successfully developed the software of strength calculation and checking of volute case for the first time, which can be installed itself. The running results of the program are accurate, so the program has great prospects in application.This program has lots of advantages, such as friendly interface, operating simply and so on. It is also compatible with the supporting software, which can provide fine foundation for expansion of the program, transplantation of the code and commercialization of software.
