The Mechanical Properties Of A Shipboard Radar

The level of structural design of radar systems for the electrical performance of radar has an important effect. The work of structural engineers in the design of the structure muse be based on the quality of the provision of the stiffness and strength of radar system requirements normal operating conditions to ensure the required work and damage does not occur for the harsh conditions. The finite element method and dynamics of multibody systems method be introduced in various stages of product design to understand the mechanical response of radar structure of the situation and to provide guidance for the structural design and verification support.In this paper, hydrodynamic software AQWA has been used to simulate the center of mass displacement over time of dynamic in different sea conditions. A finite element modal for radar system and antenna component modal are established and calculated. The area less prone to stiffness has been found according to the structure of the vibration modes. Calculation of the radar system at the strength and stiffness of these loads can meet the design requirement. Further improve the structure of the static properties of programs has been proposed. A radar system dynamics modal has been established and simulated the dynamic response of radar system by the shake of ship. This work will provided a useful reference for the radar antenna and radar-seat design.
