Signal processing of vibration signals for cable tension monitoring
【摘要】 本文简要介绍了振动法测量斜拉索索力的原理,研究了索力测试中振动信号的处理方法,并对各种方法所能达到的测量精度进行了分析,该文的结论对于快速准确的得到斜拉索的索力值具有一定的指导意义。
【Abstract】 The stayed-cables of cable-stayed bridges aremain load-bearing components.Cables’ tension is one of the most important criterion for judging if a cable-stayed bridge is in order.The random vibration method is often used to mensure the tension forces in the cables.In this paper,principles for measurement of cable tension based on frequency analysis are discussed.Signal processing of vibration signals for cable tension monitoring is studied.
