轨道交通与路面交通振动对实验室环境的影响测试

Influence Test on Rail Transit&Pavement Traffic Vibration on Laboratory Environment

当前城市快速发展,城市轨道交通建设越来越多,由此引起的环境振动问题也备受关注,尤其对有精密仪器的办公厂房或实验室。以上海市浦东新区计量质量检测所(惠南分部)为背景,在实验室内布置振动传感器,通过测试工作日轨道交通运行、道路车辆运行和轨道交通停运时不同情况下的振动响应,分析和评估不同交通工况下的环境振动对实验室内精密仪器正常工作的影响,以便采取必要的减震措施确保精密仪器能正常工作。

With the rapid development of cities in current,more&more urban rail transit construction have been completed,the environmental vibration problems caused by them are also of great concern,especially for office plants or laboratories with precision instruments.With Shanghai Pudong New Area Metrology&Quality Inspection Institute(Huinan Branch)as the background,the vibration sensors are arranged in the laboratory to test the vibration response of the rail transit operation,road vehicle operation&rail transit shutdown in different situations on working days.Analyze&evaluate the impact of environmental vibration under different traffic conditions on the normal work of precision instruments in the laboratory,so as to take the necessary shock absorption measures to ensure that the precision instruments can work normally.
