摘　　要：某船典型环境下,HVAC风管在管内风速风量的激励下,产生明显振动。采用安装橡胶减振元件及消音装置等措施后,HVAC风管振动下降最大达10%以上。本试验研究风管安装相关措施对管路振动的影响,发现橡胶垫的厚度、硬度等材料参数对风管路振动传递影响呈复杂关系。其中,橡胶垫的减隔振效果随着厚度的增加不断提升,最终趋于稳定效果,并且软管径向安装偏差对管路各方向振动亦有较大影响,为该型船减隔振措施提供一定参考。The typical environment of a ship,where the HVAC ducts generate significant vibration under the excitation of the wind speed and volume in the duct.After the installation of rubber vibration damping elements and silencing devices,the HVAC duct vibration was reduced by up to 10%or more.This test studied the influence of the measures related to the installation of the duct on the vibration of the pipeline,and found that the material parameters such as the thickness and hardness of the rubber pad had a complex relationship on the vibration transmission of the duct,in which the vibration reduction effect of the rubber pad increased with the increase of the thickness and eventually tended to stabilize the effect,and the radial installation deviation of the hose also had a greater influence on the vibration of the pipeline in all directions,which provided a certain reference for the vibration reduction measures of this type of ship.
