本文根据梁滩船闸侧墙上实测得到的记录,识别出船闸侧墙的前四阶固有频率,阻尼比及有效振型参与系数.文中给出了计算结构各阶动态弹性模量的方法,并根据识别出的固有频率求得前四阶动态弹性模量.
In this paper, the first four natural frequencies, damping ratio and effective mode participation coefficients of the side wall of the ship lock are identified based on the records obtained from the actual measurements on the side wall of the Liangtan ship lock. The methods for calculating the dynamic elastic moduli at each order of the structure are given. The first four-order dynamic elastic moduli are obtained from the identified natural frequencies.
