| Reliability design is the most important and critical aspect to ensure the reliability of the mechanical products. At present, steel cutting machine parameter system development as mechanical transmissions have been widely used in various fields in the national economy and defense industry and their demands are increasing. Although a lot of companies nowadays use CAD softwares to shorten the production cycle and improve the design quality, but these softwares are generally developed with conventional design methods, lacking the capability of reliability design. As gear modeling is very difficult in the three-dimensional modeling, if the new three-dimensional parts and components models are directly derived according to the sizes of steel cutting machine parameter system development designed by the CAD software, the workload of the designers will be greatly reduced and the design efficiency will be improved. What's more, it facilitates the follow-up finite element analysis, virtual manufacturing and CAM, etc. Basing on this, this dissertation carries out the research and development of the two-stage cylindrical steel cutting machine parameter system development parameteried CAD system. Main tasks are as follows:Development of conventional reinforced cutting machine design and reliability design second development software. Using vc + + 6.0 integrated development environment, using object-oriented technology and database technology, Pro/E second development kit Pro/TOOLKIT write second development application, design interface convenient user Settings reinforced cut-off machine raw data and conduct product developing, implementing reinforced cut-off machine parts conventional design and reliability design, and cutting machine parts model steel component model of virtual design and virtual assembly. Using Pro/E of parameterized modeling functional structure parts and components, and 3d model model derived reinforced cut-off machine parts and new assembly component model. |
