【摘要】 针对如何确定装配环境下待装配体特征之间的装配关系,提出了装配特征模块化的虚拟自动装配方法。通过分析单一零件和子装配体的装配特征,将装配特征分类存储为不同的功能模块,采用继承的方法,利用装配数据模块和装配关系模块实现装配,由此保持了设计过程中产品装配特征数据的一致性。以标准渐开线直齿圆柱齿轮为例详细介绍了这种方法的实用性和优越性。更多还原

【Abstract】 In order to ascertain the assembly relationship between assembly features of the parts being assembled under the assembly environment,the paper presented a new way for virtual automatic assembly based on assembly features’ modularized. This method analyses the assembly features of the single part or sub assemblies and then saves the features as different function modules. Using inherited way to finish assembly action with assembly data module and assembly relationship module which can ensure the consistency of data of the assembly features during the design. Taking involute straight teeth gear for example to explain the practicability and superiority of this method .更多还原
