To reduce the vibration of a ship’s high-temperature pipeline, a long coated damping structure (LCDS) with entangled metallic wire material (EMWM) is proposed in this paper. The structural analysis of the long coated damping structure for pipelines is carried out. The theoretical analysis indicates that increasing the thickness of the damping layer in a particular range can improve the vibration attenuation effect of an LCDS. Additionally, experimental verification confirms this analysis after an experimental system for pipelines. From the results, it is observed that increasing the thickness of the coated layer can effectively improve the damping property of LCDS to a certain extent. The change of the coated length and the temperature has little effect on the vibration attenuation effect of an LCDS, indicating that the LCDS can work well in a high-temperature environment.

基于长涂层阻尼结构的船舶高温管道减振分析与试验研究

为了减少船舶高温管道的振动，本文提出了一种带有缠结金属丝材料（EMWM）的长涂层阻尼结构（LCDS）。对管道长涂层阻尼结构进行了结构分析。理论分析表明，在特定范围内增加阻尼层的厚度可以提高LCDS的减振效果。此外，在管道实验系统之后，实验验证证实了这一分析。从结果可以看出，增加涂层的厚度可以在一定程度上有效地提高LCDS的阻尼性能。涂层长度和温度的变化对LCDS的减振效果影响不大，
