Key Technology of Digital Mock-up Research and Development

In order to research the key technology in the proceeding of research and development of Digital Mock-up,a four-wheel motorcycle models is taken as an example to analyze the methods of modeling parts of the virtual prototype and to expatiate the key parts of reverse engineering in designing the cover.Based on CAD software,a sub-assembly and a large-assembly with four-wheel motorcycle prototype parts are taken to study the constraints,interference and other problems during the assembly process.Through the cooperation of the digital dummy and Digital Mock-up,the RD of Digital Mock-up is more useful in practice than before.Finally,based on ADAMS/CAR software,the characters of the multi-body dynamics are analyzed to resolve the problems and defects appeared in RD.Therefore,it is possible to achieve a high-quality,high efficiency and low-cost equipment design and manufacturing through taking the optimal digital mock-up instead of physical prototype.
