Abstract
Hydraulic valves are one of the important components in hydraulic systems .The main function of these valves is controlling the flow rate of the fluid,the flow direction and the fluid pressure in hydraulic systems .Because of the hydraulic valves are the only components that can be controlled in a hydraulic system, the stages of construction and performance of these valves will have the greatest efficacy on the performance in a hydraulic valve .In this research, the affecting of three input factors such as the Spool surface roughness , the Spool diameter and the Spool cylindrical geometric tolerance as significant factors affecting in piece construction and input effect has been studied and the fluid leakage and response time of the hydraulic valve are output factors. For this purpose, Taguchi optimization method, full factorial is selected. To accomplish the testing design, the enough pieces are made in three different size levels. Therefor in two groups, tests have been done for measuring fluid leakage and response time. Results after reviewing in Minitab software have been plotted and analyzed .To verify the results, eight new specimens have been prepared randomly and the results were obtained in a regression model analyzing and its error rate has been determined. The error rate was within acceptable limits.
