基于烦恼率模型的环境振动舒适度评价

Comfortability evaluation of environmental vibration based on annoyance rate

本文对遂渝高速铁路无碴轨道试验段客车运行引起的环境振动进行了现场实测,在此基础上基于烦恼率模型对环境振动舒适度进行了评价。由环境振动引起的烦恼率随距离增大而减小,衰减速度由快逐步趋于缓慢,在距离轨道一定距离后引起的烦恼率值低于限值。烦恼率值随车速增大而增大,宜在实测区域控制车速或增加减振措施,以降低其对周围环境的影响。本文给出了基于烦恼率模型的环境振动舒适度评价分析方法。

This article is about test section of ballastless track of Yusui rapid transit railway, to test the shake of ambient vibration at locate, basically, about annoyance rate model, evaluate the comfort level . To get the result, comfort level connect with the distance, more distance less comfort level , and the rate of decay get slowly. Sufficient far away from the track, comfort level is under the limit value. Comfort level is combined with the speed of the train, accelerate the speed, more comfort level value. Thus, Control the speed of track at the test field to decrease the effect of environment is necessary. This article offers the analysis methods of environmental vibration based on annoyance rate.
