摘　　要：由于复杂三维产品模型中,零部件产品模型数量庞大,层次结构深,结构关系复杂,显示速度慢,不利于工艺设计过程中对模型的浏览和引用。通过对三维数字化工艺设计模型的研究,对MBD模型的构建进行定义,采用自适应哈夫曼无损压缩算法对三维模型的数据信息进行压缩处理以达到MBD模型的轻量化,使数据占用内存空间小、传输快,适应数字化工艺设计应用的要求。In the complex three-dimensional product model,it is not conducive to browsing and referencing the model in the process of process design due to huge number of component product models,deep hierarchical structure,complex structural relationship and slow display speed.The research on the three-dimensional digital process design model is carried out to define the construction of the MBD model,and with the Adaptive Huffman lossless compression algorithm,the data information of the three-dimensional model is compressed and processed to achieve the lightweight of the MBD model,so that the data takes up less memory space and transfers fast,which meets the requirements of digital process design application.
