【摘要】 建立缆索张力智能测量仪的三点式加载力学模型,系统分析研究了测量仪将夹持点分别按两端铰支、两端固定和考虑缆索影响的弹性支座情形,得到缆索张力的上下限值和实际测量值表达式,通过二次测定的方法,导出了更合理的"三点弯曲法"在线检测索张力的计算公式。更多还原

【Abstract】 To set up a mechanical model of three-point loading for the intellectual measuring equipment of cable tension,the cases for elastic support with two ends of hinged support and those of fixed support with consideration of the influence of the cable were systematically studied.The equations for the upper and lower limits of the cable tension T as well as those for the real measured values have been obtained.A more rational equation for online measuring the cable tension by "Three-point Bending Method" has been derived through secondary measurement.更多还原
