Abstract
This paper suggests some methods for designing and simulating of a hydraulic system. These methods are contained the way of components selection and arrangement. Furthermore these methods present the governed equations of each element and simplification and solution of them. In this paper practical rules of selecting key element in a servo-proportional circuit are presented. Comparing the results of modeling and actual tests in real conditions shows an acceptable approximation between them which causes increase in reliability of mathematical simulation of such systems. Our goal is finding some optimum techniques for designing of a hydraulics system without any needs to practical tests causing big time and costs saving. Test of designed hydraulics circuit in real conditions need repetitive setting of the machine for the new parameters causes diversion of the machine pre-set parameters that this action needs to consume a big capital and rather much time to re-set the machine and return it to work in real condition. It may be provided a dangerous situation to cause to neglect some first condition in solving the mathematical equations that is not ignorable in real condition and eliminated mistily that may destroy the machines in some cases. Worthy of mention is that simulating using a math model that really closes to act is very economical and time saving also it doesn't need to change in set of machine to experiment and several experience can be done just by a change in amount of a variable and check its result. From the viewpoint of industrial applications, the developed techniques may provide useful references for scholars who work on this.
