摘　　要：装配序列规划是装配过程中的重要环节,针对装配过程中遇到的装配效率低、装配组合数爆炸等问题,提出了一种并行装配序列自动生成的方法。首先对所有的产品零件进行编码,并通过连接关系和自由度的计算来划分子装配体;然后基于子装配体获得干涉矩阵,通过对各层零件和子装配体的二维拓扑图进行分析,规划并行装配;最后用实例验证了该方法的可行性,为虚拟装配技术在机械领域的应用奠定了技术基础。Assembly sequence planning is an important part of the assembly process.To solve the problems of assembly efficiency and huge combinatorial number among the parts in the assembly process,an automatic generation method for parallel assembly sequences is proposed.Firstly it encodes all product parts,and divides the sub-assemblies through the calculation of connection relationships and degrees of freedom.Then it obtains the interference matrix based on the sub-assembly method.By analyzing the two-dimensional topology diagram of each layer of parts or sub-assemblies,the parallel assembly is planned.Finally,an example verifies the feasibility of this method,and lays a technical foundation for the application of virtual assembly technology in the field of machinery.
