Engineering Analysis and Research on Connection Plate of Vehicle Radar Antenna Pedestal

According to the usage of vehicle radar antenna pedestal connection plate, this article analyzes and compares the structure characteristic of welding and casting. We decide to adopt the casting structure and use cast aluminium ZL101A. Based on the connection plate of using conditions, we analyze the deformation and stress of connection plate by the finite element analysis software. The design is in line with the material allowable requirements and to meet the requirements of the system stiffness.
