摘要
基于拉索振动力学模型,建立了频率与索力的数学关系。提出运用实测振动频率推算索力及频率点所对应振动阶数的计算公式,给出采用相邻频率值推算出的频率阶数偏离整数程度来评价索力测量结果可靠性、合理性的方法。针对拉索振动特点及索力检测应用环境开发出一款新型索力检测仪,其实用性、合理性已在实际工程应用中获得验证。
Based on the mechanical model of cable vibration,the mathematical relationship between frequency and cable tension is established.Using the measured natural frequency,the cable tension and order of natural frequency are calculated,and a method to assess an assessment method for the reliability of the results is given.A new type of cable tension tester is developed for a cable vibration characteristics and cable tension measurement application environment.The practicality and reliability of the tester has been verified in practical engineering applications.
