Abstract
This paper deals with the improvement of OHC-Sim which is a simulation package for the design of an oil-hydraulic circuit and analysis of its dynamic characteristics. To make the design and improvement processes of an oil-hydraulic circuit more effective and systematic, OHC-Sim was developed with the support of JHPS (the Japan Hydraulics and Pneumatics Society). It has been improved and enhanced in the research committee of JHPS. It includes a user friendly graphical user interface in Windows 95® environment, and provides easy design and improvement of an oil-hydraulic circuit on the basis of simulated dynamic behavior by a personal computer. In this paper, the structure of the oil-hydraulic component icon and how to connect component icons in OHC-Sim are emphasized, and have been improved to make OHC-Sim more useful. In addition, through examples, the main features of OHC-Sim are shown.
