摘要: 本文采用雷兹(RITz)迭代原理,对全桥进行模态分析.根据列车加载试验,得出了该桥振动位移、自振频率及冲击系数.

关键词: 窄轨弯桥, 动态测试, 模态分析

Abstract: In this paper, adopting RITZ iteration method, the medel analysis of a two-way curved arch bridge is auomplished,and the vibration displacement, self-vibration frequency,and impact factor are presen ted based on the train-load test.

Key words: narrow-gauge curved-bridge, vibration test, model analysis
