Fully automated diagnostic system development for hydraulic motor performance

抄録

In this study, the system that can automatically test comprehensive performance in the hydraulic motor and can be used as test equipments for the development of the hydraulic motor is designed and developed. The effort focuses on the development of test software that analyzes collected data from the hydraulic motor and evaluates its performance, and further on building of test equipments. Test items consists of 12 including the efficiency test, and these tests are carried out full automatically. In particular, the volumetric test is, in general, done by separating the loading part in the hydraulic motor, but here it is carried out through unloading conditions only by controlling the charging pressures in this system. In controlling the test equipment, both open loop and closed loop controls are applied resulting in stable, fast, and accurate test conditions. This system includes not only function of performance test but also capability of calibration and self diagnosis. It also involves 3D graphic contour map plotting and analytical techniques.
