随着科学技术的迅猛发展,防振研究越来越受到人们的普遍重视。采用防振台来减少振动对科学研究和生产实验所带来的不利影响,仍是当前防振措施中最重要的方法之一。防振工作的研究,实际上包含二个内容:一是自然界微小振动(亦称地球脉动)的研究,其颇率大约2-3Hz左右;另一是人工振动(它包括一切机械、人为的冲击或振动)的研究,其频率大约在3-80Hz左右。防振工作台的研制,就是为了尽可能地减少人工和自然振动所带来的有害影响。工作时,尽可能地隔离一切人为的冲击或振
With the rapid development of science and technology, anti-vibration research has been paid more and more attention by people. The use of vibration isolators to reduce the adverse effects of vibration on scientific research and production experiments is still one of the most important measures in current anti-vibration measures. Anti-vibration work research, in fact, contains two elements: First, the natural micro-vibration (also known as the Earth’s pulsation) research, the rate of about 2-3Hz or so; the other is artificial vibration (which includes all mechanical and human impact Or vibration) research, the frequency of about 3-80Hz or so. Anti-vibration table developed, is to minimize the harmful effects of artificial and natural vibration. When working, as far as possible to isolate all the man-made impact or vibration
