Method for acquiring evaluation point stress time domain value by utilizing tower crane operating data

Abstract

The invention relates to a method for acquiring evaluation point stress time domain values by utilizing tower crane operating data, belonging to a method for acquiring the evaluation point stress time domain values by utilizing large-batch load data collected by a tower crane operating data recorder. The invention mainly solves the technical difficulties of small collected data sample size, limited collected structure position and the like in the traditional methods. The method for acquiring the evaluation point stress time domain values by utilizing the tower crane operating data comprises the following steps of: (1) collecting real-time operating data of the hoisting capacity and the like of the tower crane by using the data recorder; (2) processing the collected data; (3) establishing a structural calculation model of the tower crane; (4) calculating the internal force and the stress of structural rod pieces at a certain moment; (5) enabling the stress value at the certain moment obtained in the step 4 added or subtracted by a corrected value to obtain the corrected stress value; and (6) repeating the steps to obtain structural internal force and stress data corresponding to multiple moments, and collating the data into stress spectrum data.
