Abstract
Abstract— Hydraulic actuators have a wide range for industrial applications, making them an attractive research point for engineers and rescarchers to improve existing ones and/or to develop new ones with high performance levels. the improvement of existing onces can be achieved by optimizing operation parameters for optimal responses. In this study, Taguchi design of experiment (DOE) L9 orthogonal arrays (OA) with 3-levels and 3-factors (hose length, lifting load, and pressure) are carried out to investigate the affects of operation parameters on performance measurement of actuator velocities for double acting cylinder. The analyses of signal-to-noise ratio (S/N) and variance (ANOVA) are employed to determine the optimal operation for optimal extension and retraction velocities. The obtained results show that actuator extension and retraction velocities are significantly incresed to 195.7 mm/s and 215.1mm/s (3.4 and 1.8 times higher), when compared with the initial conditions of 57.1mm/s and 120.4mm/s respectively. This significant improvement on velocities enhances hydraulic actuator efficiency and thus longer service life time for this set of experiments.
