摘　　要：针对当前航天壁板工件批量少、改型多,三维工序模型设计效率低、重复劳动多的问题,提出了基于用户自定义的壁板类工件MBD工序模型设计方法。通过分析壁板类工件,将壁板类工件特征分为槽腔、筋、孔特征,建立其三维参数化特征模型,并结合MBD标注,形成完善的用户自定义特征库。以DFM方式综合应用UDF特征实例,实现壁板工件工序模型的快速生成。最后,通过实例验证了提出方法的可行性和有效性。该方法可为壁板工件的MBD三维工序模型的快速生成提供技术参考。A model based definition （MBD） process model design methods for a panel - type parts based on user - defined feature（UDF） is proposed. This theory is to solve low design efficiency and reworks problem of three - dimensional process model. When analyzing panel - type parts, features of the panel - type parts are divided into groove cavity, tendons, hole features, then we set up different feature parametric mod- eling and MBD three -dimensional mark, thereby we form a complete UDF library. Process model of panel parts is established, with application of UDF feature in DFM mode as an example. At the end of the paper, we also verified feasibility and reliability of the method. The method can provide technical reference for the rapid generation based on MBD three -dimensional process model.
