Experimental Study on Rail Surface Shortwave Irregularity @@in Urban Mass Transit
摘要
Abstract
Spot test of rail surface short-wave irregularity in Shanghai rail transit and speed-increasing line is conducted. The amplitude distribution characteristics of rail surface shortwave irregularity analysis are analyzed based on stability test. Roughness of rail surface is analyzed and evaluated using BS EN ISO3095. The results show that rail surface shortwave irregularity meets the stability test requirement of significance level 0.05. Regularity in joint area of Metro Line 1, Metro Line 2, Metro Line 3,the Huning Line and Hukun Line is 25.3,21.7,22.2,17.8 db,and 10.2 dB higher than the ISO3095 limit respectively. Difference value between ISO3095 limit and non-joint area of Rail Transit Line 3,Huning Line and Hukun Line is 10.8,-4.2 and -8.3 dB. Rail surface roughness in rail transit is worse than that in speed-increasing lines,and the state of rail surface in joint area is worse than that in non-joint area.关键词
