EXPERI_VIENTAL STUDY OIL THE PERFORMANCE ESTIVIATION EFFICIENCY MODEL OF A HYDRAULIC AXIAL PISTON MOTORS

Abstract

Performance of a hydraulic piston motor is very difficult to estimate in advance before experiment. But it is highly required because, if an efficiency model for performance estimation is already in hands, the model enables one to design a hydraulic motor with good efficiency at a designated operating point. Recently such a performance estimation model is developed by H.S. Jeong. In this paper, validity and accuracy of the performance model is studied by comparison with experimental efficiency test data.
