Problems solved by technology

In terms of signal transmission: with traditional signal acquisition and transmission methods, the power supply cannot be guaranteed, the operation of the test scheme is difficult, and the signal attenuation is caused by too long signal lines; The energy of the law is not enough to stimulate the iron tower, and it is obviously unrealistic to use artificial incentives, and the effect is not satisfactory.

Abstract

The invention provides a testing method of a vibration response test for a high-tower structure of transmission line of transmission of vibration signals and stimulation by taking wind load as external environment in a wireless mode. The method has the characteristics of simple and convenient operation and analysis and higher precision compared with the traditional vibration response testing means in a wired transmission and hammer method. Therefore, relational environment parameters motivated by environment are confirmed through a meteorological environment monitoring device, the vibration response of an iron tower is tested by the selected accelerating sensor, the test data of the vibration response of the high-tower structure of transmission line is transmitted by applying the wireless sensor, and finally modal mode parameters of the high-tower structure of transmission line is confirmed through the back-end process of the monitoring system.

Description

technical field [0001] The invention belongs to the field of vibration testing in the mechanical performance testing of iron tower structures of transmission lines, and in particular relates to a vibration testing method for high tower structures of transmission lines. Background technique [0002] The vibration state of the transmission line tower structure is related to the external disturbance characteristics and the dynamic characteristics of the structure itself. The dynamic characteristics of the structure generally refer to the vibration frequency, mode shape and damping ratio of the structure. This parameter is only related to the material properties, stiffness, and damping ratio of the structure itself. It is related to weight, constraints, etc., and has nothing to do with external loads. Although the natural frequency and mode shape of the structure can be obtained through theoretical calculations, the dynamic characteristics obtained through testing are still of g...
