悬索桥吊索锡青铜轴套磨损性能和使用寿命试验研究

为了了解悬索桥吊索的锡青铜轴套的磨损性能和使用寿命,设计了锡青铜轴套磨损试验,模拟实际吊索的受力和低速摆动情况。试验结果表明,冷却水能够有效降低销轴由于磨损产生的热量;随磨损循环次数的增加,轴套内径逐渐增大;固体自润滑剂可以大大提高轴套的耐磨性能;锡青铜轴套的使用寿命超过33年,耐久性明显优于DU轴套。

Experiment Research on Wear Properties and Service Life of Tin Bronze Bearing Bush of Hangers on Suspension Bridges

In order to study the wear properties and service life of tin bronze bearing bush of hangers on suspension bridges, Wear test of tin bronze bearing bush is designed by simulating the force and swing of hangers. The results indicate that cool- ing water can reduce the heat generated by wear of pivot effectively. The diameter of bearing bush increases with increasing cycles of wear. Solid self-lubricating material can greatly improve the wear properties of bearing bush. The service life of tin bronze bearing bush is more than 33 years,of which the durability is significantly better than DU bearing bush.
