摘要

Hydraulic control systems are essential components in various applications, and they utilize fluid mechanics principles to regulate the movement and force of hydraulic actuators. Fluid power control systems are widely used in automated systems such as manufacturing, food processing, mobile applications, aircraft wing designs, and aerospace. This study investigates, both theoretically and experimentally, the effects of fluid temperature, system load, and stiffness on the static and dynamic performance of a linear position control system using a hydraulic servo control valve and actuator. A system was built to conduct real-time experiments. This study aims to analyze the impact of these parameters on the flow rate, supply pressure decay, stroke period, piston displacement frequency, and bandwidth. Ultimately, the goal is to provide insights for optimizing the system design to achieve the most effective control of the hydraulic actuator. The results indicate that temperature significantly affects the flow rate, stroke duration, and supply pressure decay, highlighting the need for precise temperature control to ensure consistent performance. It was also found that increasing the load and stiffness reduced the system response, as evidenced by the decrease in the bandwidth frequency. These results emphasize the critical role of considering temperature, load, and stiffness when designing and operating hydraulic control systems to achieve optimal performance, reliability, and efficiency in various applications. Future research should explore alternative system designs and control techniques, particularly at higher loads and stiffer configurations, to further optimize system performance.
