摘要
Abstract
This article discusses a new analysis method for road quality identification in the field of open-pit mine transportation,and analyzes the three-axis acceleration of mining trucks in detail by using frequency analysis filtering technology,and obtains the specific data from experiments.The triaxial frequency analysis method can reduce the data storage requirements and improve the computing performance.Compared with the time domain analysis,the method provides better analysis performance in terms of periodicity,vibration,comprehensiveness,etc.,which can obtain more realistic and accurate data by filtering noise.The operating frequency of the mining card is less than 30 Hz,and the external noise is greater than 40 Hz,and the quality results of the mining truck in the three axes are obtained through the eigenvalue calculation,and there is a strong correlation between the road quality results studied at the three axes.关键词
