车桥耦合振动的研究

Research into vehicle-bridge coupled vibration

通过对铁路提速现状中出现的部分桥梁的承载力及结构振动的特性不能满足提速要求的问题,提出进行车桥耦合振动研究的必要性、研究方法及其研究意义,以使既有桥梁技术改造决策更加科学,铁路提速更加安全可靠。

In light of the problems that the bearing capacity and structural vibration characteristics of partial bridges can＇ t meet the requirements of railway speedup, the author proposes the necessity, method, and significance to carries out research into vehicle-bridge coupled vibration, in order to make technical reconstruction of established bridge more scientific and railway speedup safer and more reliable.
