This study targets the research task of load spectrum construction and integrated design method for high-torque hub drive systems. Research on load spectrum testing and construction of the XDE240 mining dump truck hub drive system was carried out to achieve synchronous testing of multi-point and multi-parameter load spectrum signals of the XDE240 mining dump truck hub drive system under complex dynamic working conditions, thereby solving the problem of missing load spectra for domestic high-torque hub drive systems.
Based on the signal demand calculated from load spectrum data and the characteristics of the overall signal data of mining dump trucks, the method of real-time collection of vehicle CAN signals was adopted to obtain data including motor, engine and vehicle state information, specifically motor torque, motor speed, real-time cargo weight, hydropneumatic suspension pressure, engine speed, vehicle running state, electric braking state, front axle braking pressure, rear axle braking pressure and loading braking signal.
According to the application status of XDE240 vehicles from XCMG Mining Machinery Co., Ltd. in domestic mining areas, load spectrum data testing under actual operating conditions of this model was conducted at Jiangxi Copper Mine and Yulin Coal Mine in Shaanxi Province, with a fixed sampling period of 100 ms. The load spectrum test working condition data of 240-ton class mining dump trucks were obtained.
A load data processing scheme was designed, and the statistical processing of load spectrum data was realized through the steps of load spectrum data preprocessing, typical working condition classification processing, statistical calculation of typical working condition data and compilation of load spectrum results, finally outputting the load spectrum results of the 240-ton class mining dump truck hub drive system. The total data volume is 2.22 MB.
