| Abstract: |
Currently, indirect measurement using dynamic data from cable is widely used measuring the natural frequency of cable from the accelerometer attached to the surface and convert the data into tensile force. However, it sometimes requires many hazardous works such as attaching the device on the surface of cable, writing it with data logger, etc, which could hinder the safety of workers in the middle of cable. New measurement system(laser vibrometer tension measuring system, LVTMS) using wireless laser-vibrometer is developed to eliminate the unsafe works and adjust the cable tension force as well. Through the LVTMS, field engineers are able to figure out the cable tension force in no time while standing on the field. In addition, the result by the previous method is to be compared. As a result, the LVTMS is proved to be accurate and reliable |
