地铁与路面交通振动对精密仪器的影响测试
Measurement of vibration influence on sensitive equipment induced by metro and road traffic
摘要
Abstract
In order to estimate traffic-generated vibration influence on sensitive instruments in a laboratory building of one research institute, vibration measurement was performed in the laboratory. Com pared differeny traffic conditions with vibration criteria of TEMs for installation, results show that floating slab track with steel spring is efficient to mitigate the train-induced vibration level. Environmental vibrations induced by traffic are larger than the limits of criteria and affect the instruments in the laboratory. Some more passive isolation measures should be taken to ensure instruments could be installed and work without vibration disturbance in the laboratory. The work frequencies of passive isolator are suggested no: to be larger than 4Hz and its transrmssi bility should be at least 5.5 dB around 5 Hz.关键词
