基于船用风管连接件的结构设计与减震降噪研究
Research on Structural Design and Vibration Reduction and Noise Reduction Based on Marine Air Duct Connectors

在分析传统船舶风管与连接件发展现状的基础上，提出一种船舶用风管减震降噪的连接件。包括纵管、横管等结构上的优化改进，将缓冲座、四个插板、八个卡块、八个推板分别应用于减震机构、固定机构、限制机构、推出机构。从而降低风管震动产生的噪音，提高风管与连接件之间的密闭性，便于快速拆装与日常维修维护。
Based on the analysis of the development status of the traditional ship air duct and connector, a kind of connector for shock absorption and noise reduction of ship air duct is proposed. Including the optimization and improvement of the structure of the vertical pipe and the horizontal pipe, the buffer seat, four insert plates, eight clamp blocks and eight push plates are respectively applied to the damping mechanism, the fixing mechanism, the limiting mechanism and the pushing mechanism, so as to reduce the noise caused by the vibration of the air duct, improve the air tightness between the air duct and the connector, and facilitate the rapid disassembly and daily maintenance.
