摘要
由于船舶噪声对城市环境和人民群众生活的影响日益突出,城市航道船舶噪声污染已成为长江上游多个城市急需解决的社会焦点问题。为控制船舶噪声,在现场监测和走访调查基础上,从降低声源噪声和控制噪声传播途径着手,采取了设计制作船用隔声装置控制船舶机械噪声的方法,并同时解决了柴油机的进气和散热问题,以减小对机组功率的影响。经理论研究、设计计算、实验分析和应用测试,结果表明:研制出的长江上游船用隔声装置具有良好的噪声控制效果。
As the trouble that the ship noise seriously affects the environment and lives of people are becoming increasingly significant,the ship noise pollution in urban waterway has become the urgent social focus in many cities of the upper reaches of the Yangtze River.To reduce the ship noise pollution,based on the investigation and field monitoring,in the way of reducing the noise source and controlling noise transmission,it presents the design of marine acoustic insulation equipment,and solves the diesel engine suction and cooling questions.According to the theoretical research,design calculations,experimental analysis and application tests,the acoustic insulation equipment was designed and applied.It had been proved that the equipment had good effects in practice.
