Digital Assembly Simulation Technology of Antenna Pedestal Based on Measured Data

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.
