We present the articles of the first issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have developed a mechatronic system for testing gearboxes in mining shovels. The mechanical transmissions of hoist and drag winches, as well as crowd mechanisms, operate under extreme variable and shock cyclic loads, requiring strict quality control. The new test bench performs running-in and acceptance testing of gearboxes under conditions closely simulating actual operation. It supports testing for various shovel models including EKG-8US, EKG-10, EKG-12K, and others. The system uses DC motors (350 kW and 560 kW) and standard transistor converters with PWM control. The software, based on the "Pulsar-7" diagnostic system, provides manual and automatic control, multiple loading modes (constant, variable, cyclic), automated test reporting, and excavation cycle simulation. A mathematical model was developed in Simulink to simulate the running-in process. The test bench has been successfully implemented in industrial applications.
