摘要
介绍了桥梁索杆爬索机器人检测技术、磁致伸缩导波检测技术及振动法索力测试的原理及其优势。通过室内试验和实桥导波检测,充分验证了索杆导波检测技术的先进性和可靠性,试验缺陷定位误差小于3%;开展了索力振动测试法温度影响研究,当温度变化在-20℃~20℃之间时,温度对频率测试的影响系数为0.999 9~1.000 1,由此可知温度对振动法测试索力的频率影响可以忽略不计。
In this paper,the detection technology of the bridge rope climbing robot and the principle and advantages of magnetostrictive guided wave testing technology and vibration cable force testing have been introduced. Through laboratory test and real bridge guide wave detection,the advancement and reliability of the guided wave testing technology has been verified,with the testing defects location error being less than 3%. The study on temperature impact of sol-force vibration test has been carried out,when the temperature changes between 20 - 20 ℃,the influence coefficient of temperature on frequency test reaches 0.9999 - 1.0001,which has indicated that the frequency influence of temperature on the vibration method is negligible.
