一种新型阻尼器的研究
摘要
桥梁横向振幅超限一直是困扰铁路桥梁的一个重要问题。在全国铁路全面提速的大环境下,这个问题益发突出,列车速度的提高势必造成更大的桥梁横向位移,进而给行车安全造成不利的影响。传统的桥梁横向振动控制方法主要是通过改变桥梁自身刚度,达到减小桥梁振动响应的目的,但成本较高,经济性较差。耗能减振思想的提出为桥梁横向振动控制提供了一种新的思路,即用阻尼器加固桥梁。阻尼器的安装能够将输入桥梁的能量转化为阻尼器的滞回能,通过阻尼器的往复加卸载循环,先于结构消耗输入能量。这种方法的优势在于经济节省,易于更换,但目前国内缺乏该类型阻尼器产品及相关的应用研究。本文研究的正是这种新型阻尼器。
