Summary: | Fluid power systems, together with electronics, play an important role in today’s modern society and have applications ranging from heavy lifting in construction to precision motion control in the aerospace industry. Effects of hydraulic parametric variation on system response thus need to be analyzed to better understand and design entire fluid power systems. This report focuses on analyzing the stability and speed on response of a hydraulic system with varying parameters through subjecting the system to a step input. The parameters that are varied are pipeline length, pipeline diameter and orifice diameter. Data collected shows that increasing the length and diameter of different pipes in the hydraulic system have different effects on the system response. In general, increasing the length and diameter of the pipelines reduces the fluctuations in pressure at the output and reduce speed of response. It is observed that changing the length of certain pipes in the system causes great amplification in pressure and this abnormally can only be known through the simulation of the system. Decreasing the orifice diameter would result in an increase in pressure drop across the orifice, leading to a greater settling time and a more sluggish system. |
