Cable-stayed bridge, suspension bridge and some large-scale cable-membrane analysis of beaer.The drag-line being damaged, Suo Li change (pines will occur
Relax), so as to influence structural internal force distribution and structure line style, the serious corrosion of drag-line possibly even causes fracture, and then causes knot
Structure caves in.Suo Li measurement includes vibratory drilling method, oil pressure method, stress method etc., and vibratory drilling method is because its is simple to operate, and cost is relatively low
Developed quickly in engineering monitoring field etc. factor.Vibratory drilling method tests Cable power, first to obtain the vibration number of drag-line
According to, then spectrum analysis is carried out, Suo Li is calculated using fundamental frequency (the first order frequency) in theory, but in Practical Project, differ surely
Drag-line fundamental frequency (by various influence of noises) is enough effectively obtained, but utilizes the SHG properties of flexible cable, identifies the more of drag-line
Order frequency, the multiple differences for calculating continuous each order frequency are carried out the fundamental frequency of equivalent drag-line, calculated further according to drag-line geometry physical characteristic
Cable power.
The general principle of vibratory drilling method measuring rope power is the natural frequency of vibration by measuring strand, is then carried out according to Chord vibration is theoretical
Calculate analysis and determine Suo Li.Vibratory drilling method uses environment random excitation, measures former rank natural frequencies of vibration of drag-line, is then shaken according to string
Dynamic theory analysis solves, and obtains the internal force of drag-line.
How the performance of drag-line, suspension rod is detected in the lab, new material research and development, production for instructing drag-line, suspension rod
It is significant.However, the vibration frequency detection to drag-line is carried out typically by sensor at present, vibrating sensor includes contact
Formula measures and the major class of non-contact measurement two, these sensors need to coordinate other devices together to make when using in the lab
With, it is very inconvenient, and result is inaccurate.There are not drag-line, the ability meter of suspension rod dedicated for laboratory at present.
