Lightweight design method of phased array antenna
This invention discloses a lightweight design method for phased array antennas. The phased array antenna adopts a lightweight design approach, using a composite structure of a carbon fiber mounting frame and an aluminum honeycomb sandwich support plate for the load-bearing structure. This reduces the overall weight of the device while meeting load-bearing requirements. By rationally utilizing the structural shapes of the components, the discrete structural design is transformed into an integrated functional structure design. The component structure is designed as a long strip shape, and the front and back components of the load-bearing structure are arranged in a cross shape. This method improves the overall stiffness of the phased array antenna without increasing weight. The fundamental frequency of the phased array antenna is greater than 100Hz, effectively avoiding coupled vibration between the phased array antenna and the platform. The structural stiffness meets the requirements for mechanical environmental resistance design.
