AI Technical Summary

Technical Problem

Existing vehicle-mounted satellite communication antenna installation structures are unable to effectively suppress multi-directional vibrations under complex road conditions, resulting in unstable antenna pointing accuracy. Furthermore, the fixed parameters of the vibration damping components cannot adapt to different vibration intensities and frequencies, thus affecting communication quality.

Method used

It employs three sets of piezoelectric actuators arranged in a 120° ring and combined with ball hinges, a combination of butterfly springs and viscous dampers in the passive damping layer with an elastic honeycomb structure, and a gap design between the active and passive damping layers. In conjunction with vibration sensors, it monitors in real time and triggers an active compensation mechanism to achieve multi-directional vibration regulation and broadband vibration absorption.

Benefits of technology

It improves the stability and communication quality of the antenna under complex road conditions. Through the coordinated work of active and passive vibration reduction, it achieves efficient suppression of multi-directional and wideband vibrations and extends the service life of the antenna.

Abstract

This utility model discloses a vibration damping structure for mounting a satellite communication antenna on a vehicle. It includes a mounting base plate, with an active damping layer fixedly connected to the top surface of the mounting base plate. The inner cavity of the active damping layer houses three sets of piezoelectric actuators arranged in a 120° annular pattern. Each set of piezoelectric actuators is coaxially and parallelly connected to a piezoelectric stack and an electromagnetic damper, allowing independent adjustment of output force and stiffness. A passive damping layer is positioned on top of the active damping layer, with a radial gap between the passive and active damping layers. Ball joints are installed at both ends of each piezoelectric actuator, connecting them to the mounting base plate and the passive damping layer respectively. Through the three sets of piezoelectric actuators arranged in a 120° annular pattern, combined with the flexible connection of the ball joints, independent adjustment of multi-directional vibration is achieved, effectively compensating for vibration displacements at different frequencies and improving the accuracy of active damping.
