Integration Design and Analysis of Excavator Boom Based on Cad/cae

According to the existing problems in the development of actual product and working process of excavator working device’s boom, the method of integrated design and analysis for excavator boom is put forward. The defects in the process of CAD/CAE integration are summarized, the integrated design and analysis system including parametric design of boom, database design, detail feature simplification of boom, mid-surface extraction and structure analysis is studied. The parametric model of boom is established based on parametric method, the management of model parameter is realized with the help of database technology and the rapid design of model is reached. Based on the feature of boom’s structure, the simplification rule of model is determined and detail features of boom are simplified automatically by program. The mid-surface extraction process and method of model is studied, the dimensions of model are reduced and precision of mesh is enhanced. With customization technology, the customization analysis platform of boom is developed by secondary development of ANSYS Workbench code.
