摘要
为解决用振波法测量矿井提升机的钢丝绳张力时精度较低的问题,利用振波法测钢丝绳张力的原理,推导出基于非均匀弦振动的钢丝绳张力计算公式,并提出了非均匀弦振波测提升机钢丝绳张力法。通过与均匀弦振波测力法的比较,得出该方法中的修正系数β>0.1时,提升机钢丝绳的自重相比载荷不能忽略,这是非均匀弦振波测力法的最佳适用范围。试验研究表明,基于非均匀弦振波的方法具有更高的准确性。
In order to solve the problem of low precision of the tension measurement of mine hoist wire-rope,the calculation formula of wire-rope tension based on inhomogeneous chord vibration was derived and the test method of hoist wire-rope tension by using the basic principles of the wire-rope tension measurement with method of vibration wave was developed. Compared with the tension test method based on homogeneous chord vibration,the results show that when the value of correction coefficient β is more than 0. 1 in the tension calculation formula of inhomogeneous chord,which is the best application scope of the tension test method based on inhomogeneous chord vibration,the weight of hoist wire-rope can not be ignored. The study indicates that this test method has higher accuracy.
