摘　　要：分析了目前几种产品建模方法的特点。比较了机电一体化产品组成的现有划分方法。针对以广义执行机构为主功能的机电一体化产品组成划分 ,提出了结合Matlab软件的SimMechanics工具箱建立机电一体化产品的广义执行机构模型、传感器模型和控制策略模型的机电产品组成对象建模的方法 ,为机电一体化产品方案生成后的进一步仿真分析奠定了基础。文章以特定的机电一体化产品———家用多功能缝纫机的横针机构子系统为例 ,阐明了这种建模方法和仿真技术的具体应用 。In this paper we analyzed some currently using physic syste m modeling m ethods,and compared the decomposition means of mechatronic system.According to t he 3-Subsystem decomposition method which takes the generalized actuator mechan isms as the main function of mechatronic products,we proposed a new approach for modeling of the constituent components of mechatronic products.That is combined with Matlab toolbox SimMechanics,we built the generalized actuator mechanisms,s ensor models,and control strategies database for mechatronic products.These data base forms the basic for further simulation analysis and synthesis of mechatroni c products in the integrated conceptual design environment.To illuminate the app lication of this modeling and simulation method,we studied the transverse-swing needle mechanism of multi-purpose sewing machine,modeled its subsystems then s imulated it,and the experiment arrives at a satisfactory result.
