In 2020, research on the load spectrum testing and construction of the XDE120 mining dump truck hub drive system was conducted. Synchronous testing of multi-point and multi-parameter load spectrum signals for the XDE120 mining dump truck hub drive system under complex dynamic working conditions was achieved, addressing the issue of missing load spectra for domestic high-torque hub drive systems. Based on the signal requirements calculated from load spectrum data and the characteristics of the whole-vehicle signal data of mining dump trucks, the method of real-time collection of whole-vehicle CAN bus signals was determined to acquire data information including motor torque, motor speed, real-time cargo weight, hydropneumatic suspension pressure, engine speed, overall vehicle driving status, electric brake status, front axle brake pressure, rear axle brake pressure, and loading brake signal. The load spectrum data was categorized into 12 working condition types: loading brake, full-load waiting, no-load waiting, mechanical braking, electric brake with full-load forward, electric brake with full-load reverse, electric brake with no-load forward, electric brake with no-load reverse, full-load forward, full-load reverse, no-load forward, and no-load reverse. According to the application status of XDE120 vehicles from XCMG Mining Machinery Co., Ltd. in domestic mining areas, tests on the actual operating condition load spectrum data of this model were carried out at Yunnan Zinc and Indium Mine and Tibet Julong Copper Mine, generating the load spectrum test working condition data of the XDE120 mining dump truck. A load data processing scheme was designed; through the steps of load spectrum data preprocessing, typical working condition classification processing of data, statistical calculation of typical working condition data, and compilation of load spectrum results, statistical processing of the load spectrum data was completed, and the load spectrum results of the XDE120 mining dump truck hub drive system were output. The total data volume is 1.54 MB.
