MAIN RESEARCH FINDINGS AND COMMERCIAL OFFERS

MAIN RESEARCH FINDINGS

1. A new universal high-performance method of mathematical modeling of engineering systems at the macro level (structural matrix method). The method allows objects of different physical nature, namely mechanical, hydraulic, thermal and electrical, to be simulated. It is presented in the textbook Mathematical Modeling of Engineering Systems (first edition in 1997, second edition in 2004).
2. The methodology for computer-aided functional design of engineering systems intended for obtaining optimal design solutions at the initial design stage. It is presented in the textbook Mathematical Modeling of Engineering Systems.
3. 3Mathematical models of motion of wheeled and tracked vehicles as complex multivariate probabilistic systems with nonholonomic constraints. They are presented in the monograph Design of Wheeled Traction and Transport Machines and in the textbooks: Tractors. Design, Construction and Calculation and Theory of Vehicle Motion.
4. The correlation-spectral method for modeling and investigation of nonlinear stochastic systems. It is given in the textbook Theory and Design of Automatic Systems and in the monograph Design of Wheeled Traction and Transport Machines.
5. The theory and methods of algorithm synthesis for adaptive mechatronic systems of automatic HMT control in mobile machines. It is presented in the monograph Intelligent Vehicle Control Systems.
6. The theory and methods of intelligent technologies in the systems of automatic control and diagnosis of vehicles. It is presented in the monographs Intelligent Vehicle Control Systems and AI-Based Technologies in Vehicle Diagnosis.

All these research developments are used in teaching students majoring in Automobile Construction (specialty code 1-37 01 02) and in a number of other specialties.

The most significant developments that have been implemented:

1. The family of standard hydromechanical transmissions (HMT) for heavy-duty trucks and tractive vehicles with the engine power up to 500 kW. They were put into production at OJSC BelAZ and have been used in BelAZ and MoAZ vehicles since 1980 up to the present time.
2. The automatic control system for the process of synchronization of locking elements of tooth clutches in gearboxes of airborne fighting vehicles. It was put into production at the Volgograd Tractor Plant in 1992.
3. Participation in the development of hydromechanical planetary gearboxes for BelAZ quarry dump trucks with payloads of 90 tonnes, 130 tonnes and 60 tonnes. Substantiation and selection of the kinematic scheme and major parameters of all components. The research results were implemented in dump trucks with payloads of 90 tonnes in 2007 and in the development of a new 60-tonne payload dump truck.
4. Algorithms for adaptive mechatronic systems of automatic HMT control used in BelAZ dump trucks and the software for microprocessor controllers implementing these algorithms. They are used in dump truck with payload capacity of 90 tonnes.
5. The mechatronic system for automatic control and diagnosis of hydromechanical transmissions of BelAZ quarry dump trucks with a payload capacity of 45-60 tonnes, which has been in use since 2010.
6. Development of a full range of mechatronic components for the automatic HMT and engine control system for BelAZ dump trucks. The production of components was launched at OJSC Izmeritel in 2014.
