THEORETICAL PRINCIPLES OF CAM MECHANISMS OPTIMIZATION IN TRANSPORT POWER PLANTS

Abstract

The article considers the scientific foundations of improving cam mechanisms, which are an integral part of gas distribution systems of transport power plants. The relevance of the work is due to the need to increase the efficiency of gas exchange, reduce fuel consumption and reduce the negative impact on the environment during the operation of vehicles. The main attention is paid to building a holistic theoretical optimization model that considers kinematic, dynamic, structural, technological and resource factors. As a key criterion for assessing the efficiency of the functioning of cam mechanisms of gas distribution, the value of “time-section” was chosen, which is determined by the diagram of changes in the passage sections of the valves over time. It is noted that as an indicator for assessing the “time-section” of valves, it is advisable to use the coefficient of completeness of the pusher lift diagram, which is closely related to the quality of the functioning of the gas distribution system. To implement the tasks, computer modeling and mathematical planning of the experiment methods were used, which made it possible to reduce the volume of calculations and at the same time maintain high accuracy of the results. A multiparameter optimization algorithm was proposed considering multiple constraints, which allows to ensure balanced operation of the mechanism considering the conditions of resource conservation and design automation. The results obtained should be implemented in modern transport technologies to increase energy efficiency and durability of power plants. The presented approach is the basis for further research and practical implementation in the field of designing new generation transport systems.
