摘　　要：Pro/E模型与MATLAB/Simulink模型表达方式的不一致直接影响了两者间进行联合仿真.从Pro/E装配模型到MATLAB/Simulink模型的转换分为装配模型信息的提取和接口信息转换两部分内容;前者采用的是基于特征设计技术和分层、分类的方法来提取信息的,而后者是把.xml作为中性文件将信息从Pro/E到MATLAB/Simulink间进行映射.其中后者还涉及Pro/E装配模型的约束关系到机构间运动副的转换,采用的是基于约束度的组合推理算法实现简单约束转运动副,并对螺旋法转运动副进行了理论研究.最后用转换挖掘机实例证实了上述研究方法的可行性,解决了利用Pro/E和MATLAB/Simulink进行联合仿真所遇到的相关技术性问题.The different expressions between Pro/E model and MATLAB/Simulink model affect directly co-simulation. The process of transferring the Pro/E assembly model to MATLAB/Sim- ulink model was divided into two sections： extraction of the assembly model information and transformation of the interface information. The realization of the former was based on feature design technology and hierarchical classification, the latter took. xml as a neutral file and mapped information from Pro/E to MATLAB/Simulink. Transforming constraints of the Pro/E assembly model into kinematic pair of the mechanism was the key point. The process used compositional rea- soning algorithm based on the degree of constraint to realize the transformation, and studied spiral theory about transforming constraints into kinematic pair. Finally, the experiment based on the excavator con- firmed the feasibility of the research technique. The proposed method has solved the related technological problems when the united simulation is carried out by Pro/E and MATLAB/Simulink.
