Computer-aided design of hydraulic system for special machine tools

This study focused on designing general hydraulic systems. We first reviewed the fundamental laws of fluid mechanics, properties of hydraulic fluid, commonly used system components, and typical circuits of different functions. Then, we presented and discussed the generally useful methods and tools for designing hydraulic power transmission system for special machine tools, especially for modular machine tools, showing how standardized modules with different functions can be integrated into a whole hydraulic system. Design procedures and methods for improving the efficiency of the design process are suggested and described. A few examples of using these methods and tools in designing practical and real machine are also presented.
