测索 meaning in Chinese
measuring rope
pendant wire
Examples
- The cable sag and bending stiffness effects are studied on the higher natural frequencies of cable vibration . it is found that the differences of the higher adjacent frequencies go to the fundamental frequency of the taut string theory even though the cable sag or bending stiffness is included . this unique characteristic of cable vibration is used to determine the cable tension with the well - known taut string theory
2 .考虑垂度和抗弯刚度对高阶自振频率的影响，探讨了索相邻频率之差，发现索的高阶频差就是弦振动理论的基频，利用这一特性，分析了频差法测索力的精度和适用范围。 - The cable tension plays an important role in the construction control and long - term monitoring of cable - supported structures . the engineering implementation of a vibration - based cable tension evaluation is mostly carried out based on the taut string theory where the cable tension is estimated from measured natural frequencies by use of a simple explicit formula
振动法测索力广泛应用于索结构的施工控制和健康监测，其原理是基于弦振动理论：索拉力与自振频率之间存在简单的关系，因此可以由实测的自振频率计算得到索力。 - In this paper , the fundamentals of cable forces by frequency method are introduced . the curve fitting method is utilized to get the correcting formula of cable forces and frequency through the experiment . on the other hand , a kind of catenary line cable element is introduced in this paper , owing to the inaccuracy caused by correcting struss element in fem
本文还介绍了频率法测索力的基本原理，并通过试验，利用曲线拟合法得出索力频率之间的修正关系式；其次，由于有限元计算中，索元所采用的修正杆元所带来的不精确性，对于长索其精度更难保证，因此，本文介绍了一种计算精度高、工作量小的悬链线索元。
