Abstract
With the development of modern construction machinery to the large-scale and intelligent direction, the hydraulic and pneumatic systems, as the key execution components, play an irreplaceable role in improving the performance of equipment. This study focuses on the application optimization of hydraulic and pneumatic systems in engineering machinery, and aims to explore the working principle and improvement path through the combination of theoretical analysis and experimental verification. Through the systematic combing of relevant literature at home and abroad, combined with practical engineering cases, a simulation model based on multi-physical field coupling is constructed, which realizes the accurate prediction of the dynamic characteristics of the system under complex working conditions. It is found that by introducing intelligent control algorithm and new materials, it can effectively improve the response speed and stability of the system, reduce energy consumption and extend the service life. In particular, in view of the common faults such as leakage and wear existing in the traditional system, a complete set of preventive maintenance scheme is proposed, which significantly improves the reliability and safety of the equipment. In addition, this study also innovatively applies the Internet of Things technology to the remote monitoring and fault diagnosis of hydraulic and pneumatic systems, providing technical support for the realization of intelligent operation and maintenance.
