ABSTRACT
Purpose. The main objective of this study is to develop and validate an innovative method for the design of tunnel bolters based on recurrent metamodelling. The application of this approach should help to improve the structural and functional characteristics of tunnel bolters, which play a key role in production processes at modern mining and construction enterprises.
The methods. To achieve this goal, we developed the concept of recurrent metamodelling, which combines the results of system analysis of structures and the use of CASE technologies to generate and optimise design processes for structures. This methodology allows creating metamodels of all possible configurations of tunnel bolsters, taking into account their mechanical and hydraulic properties. MATLAB Simulink software was used in the modelling.
Findings. The study confirmed the effectiveness of the U-shaped law of movement of the tunnel boring machine manipulator in terms of minimising their operating time. The developed mathematical model of the hydraulic drive, which takes into account various scenarios of the point mass movement, allows to accurately establish the laws of controlling the movement of the hydraulic distributor spool, ensuring minimal error of the results.
The originality. The developed methods and tools have significant applied value for the design and modernisation of tunnel pavers to ensure a significant increase in their performance and reliability in various operating conditions.
Practical implementation. The creation of recurrent metamodelling is an innovative technique in the field of tunnel boring machine design. Thanks to its application, it is for the first time possible to systematically analyse and optimise the design of this equipment using software tools. This opens up new prospects for improving the efficiency and reliability of tunnel bolters.
Keywords: recurrent metamodelling, tunnel boring machine, system analysis, MATLAB Simulink, hydraulic drive, design optimisation.
