The Parametric FEA System Of Box-girders Of Overhead Traveling Cranes Based On VC++ And ANSYS Interface

The product functions and quality are the primary factors to affecting its competitive power. But the main stage of deciding the functions and the quality is the design stage. Therefore, the modern manufacturing industry competition is the product design competition and the research on product design theories and methods has become the focus in academic circles and business communities. In terms of the development of cranes, it is a pressing problem to using modern design theory to improve its features and quality and further enhancing their competitiveness. The traditional design calculation is completed manly by manual ways. This is not only inefficient but also not accurate due to make a great deal of simplifications and approximations. Further more, it is not conducive to the diversification trend and the sustainable development of research and development of cranes because it is more time-consuming and costly. Therefore, in order to improve the design efficiency of overhead traveling cranes, a high efficient FEA analysis platform is established by integrating parametric technology and finite element method through using Visual C++ in this paper. Users only need to input required parameters and it can give the static and dynamic characteristics of metal structures of cranes by automatically modeling and calculating. So the process is greatly reduced. The innovations of the method proposed in the paper are enhancing the product reliability by using finite element method and shortening the research and development circle by simplifying its analytical process and avoiding lots of repetitive works.The content of the study in this paper are follows:(1) Using APDL to establish typical models of metal structures of overhead traveling cranes as the basis of parametric models.(2) Discussing on interface technology between ANSYS and Visual C++.(3) Application of Visual C++ and ANSYS software to develop a practical, convenient and reliable metal structure FEA platform of overhead traveling cranes.(4)Testing the reliability and practicality of the system by using it on the general QD10t×53m metallurgical overhead traveling crane of Hubei Yinlun Machinery Co., Ltd. and the 5t to 50t series of different span overhead traveling cranes.
