环境污染和公害,是现代工业发展过程中的一个新问题,噪声就是其中之一。近年来,在要求防止噪声的世界舆论下,各国对能减少各种机器产生的振动或噪声的金属材料进行了广泛的研究,发展也很迅速。 本文依据收集到的有关文献资料,对噪声的来源及其危害,国外高阻尼合金的发展、机理、应用作一概要的综述,并介绍了我们研究工作的一些动态。
Environmental pollution and public hazard are one of the new problems in the development of modern industry. Noise is one of them. In recent years, under the global public opinion that demands prevention of noise, various countries have made extensive research on metal materials that can reduce the vibration or noise generated by various machines and are developing rapidly. Based on the collected relevant literature, this paper summarizes the origin and harm of noise, the development, mechanism and application of foreign high-damping alloys, and presents some developments of our research work.
