摘　　要：文中对现阶段车载情报类天线座的装配流程进行梳理,提炼各零部件的关键建模特征和装配特征,筛选识别关键装配参数,构建天线座数字化装配孪生虚体。通过导入关键零部件的实测数据,以满足传动装配质量为约束,快速生成天线座实际装配仿真模型。基于Creo2.0开发天线座数字化装配仿真软件,开展装配过程仿真,提前识别装配干涉,形成垫片修配环节作业指导并向装配现场发布,消除实物预装风险,实现由实物预装向虚拟预装模式的转变。最终以某型号车载雷达天线座为应用对象,完成天线座装配仿真技术的应用验证。In this paper the assembly process of the vehicle-mounted antenna pedestal at the current stage is combed,the key modeling features and assembly features of each component are refined,the key assembly parameters are selected and identified and the digital twins of the assembly process of antenna pedestal are built.By importing the measured data of key components,the actual assembly model of antenna pedestal is generated quickly in order to satisfy the assembly quality of transmission.The digital assembly simulation software of antenna pedestal is developed based on Creo2.0,followed by assembly process simulation,the early identification of assembly interference,the formation of gasket repair operation guidance along with its release to the assembly site,the elimination of the physical pre-assembly risk and realizing the transformation from physical pre-assembly mode to virtual pre-assembly mode.Finally,taking a certain type of vehicle-mounted radar antenna pedestal as the application object,application verification of the antenna pedestal assembly simulation technology is completed.
