Manufacturing method of titanium alloy ship bulbous bow inner hull

Abstract

The invention discloses a manufacturing method for the bulbous bow inner hull of a titanium alloy ship, which comprises the following steps: positioning the inner hull linearly normal to the vertical outer shell; fixing the distance in the three-dimensional space of the tire frame of the inner shell; The method adopted in the present invention can ensure the accuracy of the inner shell molding line, balance the stress points where the inner and outer shells connect, and increase the strength of the shell. The linear normal direction of the inner shell is positioned vertically to the outer shell so that the distance between the inner and outer shells is basically consistent. The tire frame of the inner casing is fixed in three-dimensional space, which effectively controls the difference in curvature of the fan-shaped surface with different widths and heights, and improves the accuracy of coordinate values ​​in different spaces. Implement the combined expansion of parts on the grid of the inner shell, so that the expansion momentum of the shell can be adjusted to be basically the same, and the encrypted waterline and the small straight section of the rib head can improve the sampling rate of the external dimensions of the parts and the curvature of the line shape. The tightness of the structural joints is also increased.

Description

Titanium alloy ship bulbous bow inner shell manufacturing method Technical field [0001] The present invention relates to shipbuilding, particularly to the manufacture of bulbous bow inner hulls of ships, specifically a titanium alloy The material is used as the manufacturing method of the bulbous bow inner shell. Background technique [0002] The bulbous bow of the ship can not only reduce the wave-making resistance, but also increase the speed of the ship. More importantly, the built-in sonar tracks the water Under the target, measure the azimuth, distance and speed, and monitor the multi-directional underwater information, and transmit the detected information to the underwater acoustic system, Provide monitoring reports of torpedoes attacking the ship, and provide accurate data to the command system to promptly destroy incoming torpedoes. What existing my country's warship bulbous bow manufacture mainly adopts is glass fiber reinforced plastics (3201SGRP) resin mater...
