地铁列车振动对精密仪器和设备的影响及减振措施

Vibration Impact on Sensitive Instrument and Equipment Due to Metro Train and Its Reduction Measures

轨道交通对环境产生的振动问题已引起人们的重视,但是关于对精密仪器造成影响的研究成果非常少。随着城市轨道交通的快速发展和地面机构的修建,便捷的轨道交通与精密仪器的使用将形成无法回避的矛盾。因此,关于振动对精密仪器、设备影响的研究具有重要的现实意义和科研价值。为此,笔者探讨地铁振动对精密仪器和设备影响的表现,详细介绍仪器和设备允许振动的含义及影响因素等,建议采用综合减振措施,并提出综合治理及减振措施设计原则,为减振措施的选取和设计提供了参考,同时还指出了该领域中还需进一步研究的几个问题。

The envirorment vibration due to metro train has attracted considerable attention, but its impact on sensitive instalment is scarcely noticed. With the rapid development of urban mass transit and the construction of the universities, hospitals and other companies, how to reduce vibration impact on the sensitive instrument due to underground traffic becames urgent. The vibration impact on insrument and equipment is discussed; and the significance of allowable vibration and influential factors are described in detail. Comprehensive reduction measures are suggested. Feasible measures and the design criteria are put forward as the guideline in making choice and design. Problem need to be further studied are indicated.
