Aimed at the unknowable assembly status,uncontrollable assembly process,and low assembly success rate of array antennas in the traditional assembly mode,a set of array antennas adaptive assembly equipment was designed in a modular form on the basis of analysis of assembly requirements of array antennas,and its key hardware was selected and checked.The hardware control scheme and control program of the system assembly process were designed and written,and a simple virtual debugging platform was developed in combination with Unity software,which realized the functions of real-time synchronization of hardware status,simulation of model motion interference,roaming of 3D simulation environment,etc.,and verified the rationality of mechanical design and motion control scheme.
