The Joint Institute of Mechanical Engineering offers consumers the SVM-420I on-board automated system for in-place assessment of the technical condition of BELAZ dump truck motor-wheel gearboxes under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

On-board automated systems for in-wheel motor gearbox condition monitoring are sophisticated diagnostic systems used in vehicles such as electric vehicles, rail transport, and specialized equipment. These systems enable real-time monitoring of gearbox condition, identifying faults, and preventing breakdowns, significantly increasing reliability and reducing maintenance costs.

The main functions of such systems are:
1. Vibration monitoring: Analysis of vibration characteristics to identify deviations in gearbox operation.
2. Temperature analysis: Monitoring the temperature of gearbox components to prevent overheating.
3. Wear diagnostics: Assessing the condition of gears and bearings.
4. Failure prediction: Using machine learning algorithms to predict potential malfunctions.
5. Integration with on-board systems: Real-time data transmission to the vehicle's central computer.

Major global manufacturers:
1. Siemens Mobility (Germany)
- Key features: Siemens develops condition monitoring systems for rail transport, including diagnostics of gearboxes and in-wheel motors.
2. SKF (Sweden)
- Key features: SKF offers solutions for monitoring the condition of bearings, gearboxes, and other components, including vehicle systems.
3. General Electric (GE Transportation, USA)
- Key features: GE develops diagnostic and monitoring systems for rail and other transport, including in-wheel motors.
4. Nidec Corporation (Japan)
- Key features: Nidec produces in-wheel motors and diagnostic systems for electric vehicles and other transport.

The SVM-420I onboard automated system for in-place assessment of the technical condition of BELAZ mining dump trucks' in-wheel motor gearboxes (IMGs) with wireless data transmission, developed at the United Institute of Mechanical Engineering, is designed for onboard diagnostics of heavily loaded in-wheel motor gearboxes. The system enables continuous vibration monitoring and technical condition assessment of the RMK during quarry operation, assessing the remaining life of its components and promptly alerting the driver to the pre-emergency condition of the motor-wheel gearboxes. It also wirelessly (via GSM networks and internet technologies) transmits diagnostic data to quarry service departments and to the BELAZ OJSC server.

The information is published in the Catalog "100 Best Developments of the National Academy of Sciences of Belarus for the National Economy in 2022–2023," 2024, pp. 83–84. (in Russian)

A significant difference between this development and existing domestic and foreign counterparts is its ability to assess the technical condition of mobile machine drive mechanisms under variable loads and speeds.

Thanks to wireless data transmission, the SVM-420I system enables diagnostics of the technical condition of motor-wheel gearboxes in quarry dump truck operations virtually anywhere in the world.

The use of an onboard vibration monitoring system improves dump truck availability, reduces maintenance time by 15-17%, reduces troubleshooting time by 1.5-2 times, and, through timely maintenance, increases mean time between failures by at least 10-15%.

Readiness for production use:
- The system is currently integrated into the BELAZ Intelligent Global Monitoring and Predictive Analytics system, a control and diagnostic system, and features automated wireless GSM-GPRS transmission of diagnostic data to the user's mining and transport complex control system (quarry service department) and to OJSC BELAZ.
- Functional testing of the system was conducted by the experimental section of OJSC BELAZ's Intelligent Quarry Management Systems Department and the Industry Laboratory for Research, Design, and Testing of Electric Vehicles and Basic Electric Drive Components at the Research Center for Electromechanical and Hybrid Power Plants of Mobile Machines of the Joint Institute of Mechanical Engineering of the National Academy of Sciences of Belarus.
- A set of operating documentation was handed over to OJSC BELAZ.
- In 2023, a pilot batch (13 sets) of on-board vibration monitoring kits and software for visualizing the current state of hub motor gearboxes was manufactured and delivered to BELAZ OJSC for controlled operation for service operators.

The Joint Institute of Mechanical Engineering completed R&D project "Creating a prototype vibration monitoring system for in-wheel motor gearboxes and integrating it into the on-board monitoring and diagnostic system of a dump truck". A modernized version with automated wireless data transmission was developed under a contract with OJSC "Modernize the on-board vibration monitoring system to provide automated wireless transmission of diagnostic data and develop a methodology for its application on BELAZ dump trucks".
