ANTI-VIBRATION RADAR MAST FOR SHIP

摘要

The present invention provides a low vibration radar mast structure for a ship and a vibration proof design method thereof capable of designing natural frequency of a light post higher than excitation frequency of a commercial navigation region of the ship, wherein the low vibration radar mater structure comprises: the light post arranged in the center of an upper part of an upper platform; and a support installed to have a triangular structure over both the traverse direction and the longitudinal direction with respect to the light post. The present invention may avoid resonance of the light post in all the regions including the commercial navigation region and also regions lower than the commercial navigation region, thereby may prevent a damage to the light post caused by vibration occurring from resonance during real navigation of the ship. Moreover, the present invention may reduce a weight versus rigidity of the radar mast, namely may reduce a size of the upper platform and a weight of the light post thereby saving overall prime costs.
