【摘要】 通过数值计算 ,从理论上对上、下行两桥连接抑制桥梁横向振动的效果进行了深入的研究。结果表明 ,两桥连接之后桥梁横向振幅将明显减小 (减振率接近 50 )。此项研究 ,在列车提速过程中 ,为抑制类似桥梁的横向振动提出了一种简便而有效的方法。更多还原

【Abstract】 The effectiveness of suppressing transverse vibration of the bridge by joining two bridges of the up and down track were researched with the unmerical method.The results show that the amplitude of transverse vibration of the bridge will be obviously reduced(the ratio of suppressing is approach to 50%) when the two bridges are connected to each other.In this paper,a simple and effective method was presented for suppressing transverse vibration of the similar bridges in the course of train speed raising.更多还原
