1) brige automation
桥梁自动化
2) bridge vibration
桥梁振动
1.
Theoretical analysis of low-frequency noise radiated from bridge vibrations;
桥梁振动辐射低频噪声评估方法研究
2.
Based on the 1/4 models of motorcar,the model of simple supported beam was used with constant moving load to simulate bridge vibration and the half sine curve was used to simulate the bridge floor longitudinal curve when bridge upwards formed.
基于1/4汽车模型,采用常量力移动荷载模型模拟桥梁振动,以及半正弦曲线模拟桥梁上拱后所形成的桥面纵坡曲线,分别建立了由桥梁振动和桥梁上拱引起的车辆振动响应方程,分析比较了以上2种情况对车辆振动的影响。
3.
The train-bridge vibration characteristic is analyzed by this program when mix-marshalling freight trains traverse a 32-meter-span prestressed concrete simple beam bridge.
从列车在不同加载位置对桥梁的作用以及桥梁对车辆的反作用的角度出发,结合车桥的动力特性,揭示了混编货车过桥时,一般桥梁振动响应较大、轻车容易发生脱轨事故的机理——混编货车由于轴重差别显著,对桥梁产生周期性的大幅值的强迫荷载,导致桥梁振动剧烈,而桥梁的振动加剧又对轻车产生强烈的反作用。
3) movable bridge
移动桥梁
1.
The preliminary application of new materials to the movable bridge;
新材料在移动桥梁中的初步应用
4) girder bridge vibration
梁桥振动
6) bride swing
桥梁摆动
