一 发展概况 阻尼减振和降噪技术的研究与应用在国外已有几十年的历史,美国在二次大战期间曾用于核潜艇和坦克中。近三十年来,又在空间技术上取得了极为广泛而又卓有成效的应用。法、英、日、西德各国也相继在武器装用,固体火箭推进,航天与航空、运载车辆、桥梁与土木建筑、舰船、化工以及大量的环境与劳动保护工程等方面,使粘弹性阻尼结构的设计、研究与实践取得了有效的成果。它主要包括在如下方面:
A Development Overview Damping and noise reduction technology research and application in foreign countries for decades of history, the United States during the Second World War has been used in nuclear submarines and tanks. In the past three decades, space technology has also achieved a very extensive and effective application. The United States, France, Britain, Japan and West Germany have successively made viscoelastic damping systems in the areas of weaponry, solid rocket propulsion, space and aviation, vehicles, bridges and civil engineering, ships, chemicals and a large number of environmental and labor protection projects. Structure design, research and practice have achieved effective results. It mainly includes the following aspects:
