摘要：

In Order to analyze thc fatigue of concrete pump trucks, a data-driven method of compiling fatigue load spectra for concrete pump truck booms was proposed by utilizing big data analysis technology. The typical operating posture of concrete pump trucks was defined by analyzing the angle of boom inclination and pinch angle. Then, load Information was collcctcd aecording to the selected typical operating posture, and data pre-processing was performed on the collected raw signals to im-prove the data quality and make the fatigue load spectrum morc rcliable afterwards. A parametric method was used to estimate and cxtrapolate the amplitude distribution of thc tested load spectra to obtain the load spectra under the whole life cycle, and the load spectra were strengthened for fatigue verification. Thc rcliability and engincering practicability of the proposed method were verified by con-dueting tests on a large amount of data collected from 300 pump trucks of a certain model. The results provide some references for the fatigue load spectrum preparation of thc multi-joint boom strueture of concrete pump trucks. © 2024 Chinese Mechanical Engineering Society.
