Abstract


In this paper, the lack of domestic crane industry the CAD field of design and manufacture , bridge crane CAD research core object-oriented design ideas , parametric design and parametric drawing of the structure of the whole system The in-depth study , modular , serialized design . Topics open CAD ??system using object-oriented technology development , reasonable object model and a tree - like structure the abstract bridge crane class expressed bridge crane object using object-oriented technology , which encapsulates the structure of the bridge crane basic information and computational analysis and operation . Crane parametric design method of calculation using the object-oriented programming with Visual C 6.0 for developers on the Windows platform , and take full advantage of the four main characteristics of objects , classes and inheritance characteristics , build more reasonable . The process of checking the the bridge crane structural strength , stiffness , stability packaged into modules, each checking results can be used to optimize the design constraints , as long as the to input basic design parameters , will be able to automatically output the calculation process and checking results , so designers freed from the heavy hand calculations , and have more energy to engage in creative design . The system to the AutoCAD software for graphics support , command file interface parameters drawing , design software independent of the operating system environment and the software interface , and be able to use all AutoCAD system command . Object-oriented programming practices encapsulated in the SCR class , drawing call the class member functions can . Subject to the completion of the bridge crane structure - based 2D parametric drawing , in order to optimize the data or data visualization design parameters file Parametric Drawing command bridge crane . Crane CAD system based on object-oriented technology, combined with the idea of object-oriented technology and parametric design , and make full use of the relevant technology , design calculation overhead crane structure , convenient designers design , shorten the design cycle , improve work efficiency .
