XDE400 electric drive dump truck high-torque hub drive system hub bench loading and idling test data: The time range of the data is 0-3000s, covering the idling and loading periods of the bench hub system. All data were collected using the data acquisition system from M+P GmbH of Germany, with a sampling frequency of 12.5 kHz. This dataset contains the vibration acceleration values of gears and bearings in the high-torque hub drive system under given rotational speeds and loading conditions, as well as the acoustic field data of the hub drive system under specified operating conditions. XDE260 high-torque hub drive mining truck vibration and noise test data: The test subject is the cab of the XDE260 high-torque hub drive mining truck. The time span of the data is 0-1200s, corresponding to the calculation duration of the optimization program. The main test operating conditions include straight driving on smooth roads, turning, uphill driving, downhill driving, and straight driving on rough roads with potholes. Based on the acquired data, the main sources of cab noise under different operating conditions are analyzed and identified, the sound insulation and sound absorption performance of the cab is evaluated, targeted guiding suggestions are proposed for existing issues to further optimize the sound insulation and sound absorption performance of the cab.
