Abstract

A test in situ was carried out on the vehicle of Shanghai metro line 1. The vehicle vibration accelerations were obtained in different metro sections. Based on full vehicle model and the vehicle parameters of Shanghai metro line 1, time-domain numerical method was adopted. Dynamic calculations were carried out by inputting different railway track irregularities. The comparison between the calculated values and the measurement values of the vehicle vertical vibrations was made to preliminarily explore the problem of the track vertical profile irregularity of Shanghai metro line 1.

Key words
