The Dynamic Characteristics Digital Simulation And Parameters Optimized Of The Jig Alternating-Flow Hydraulic System

Based on the jig alternating-flow hydraulic system, the dynamic characterize of the system and it's parameter optimizing research was studied in this paper. The alternating-flow hydraulic technology was used to take on theory study for the jig alternating-flow hydraulic system. After comparing varied modeling methods, power-bond graph, which is an advanced modeling tool, was adopted to setup the system dynamic model. The principle and component of power-bond graph were introduced in detail as well.Modeling and simulation on the jig alternating-flow hydraulic system with computer is the general goal of this paper. By building the power-bond graph for each component of the system and ascertaining the connection between motion rule and bond-graph of the components, the single-phase jig alternating-flow hydraulic system model was build. In order to solve this model, the state-space method based on MATLAB was used, and the dynamic characteristic curve with comparatively precision has been achieved. Based on this, some groping research on multi-phase jig alternating-flow hydraulic system modeling was given in this paper.After studying the structure and work principle of the alternating-flow hydraulic system for the jig, two application modes of the capsule accumulator in this system were introduced. As an air spring, the performance of the high pressure accumulator has been analyzed. The performance parameters such as charge pressure and effective volume of the accumulator was recalculated and optimized, which makes it possible to save energy and get a reliable goal of optimizes.To study the coupled parameters of the system model, some structure performance parameters was adjusted and the affection law has been sum up. What is worthwhile to mention, a visual simulation software for optimizing parameters of the single-phase jig alternating-flow hydraulic system was developed with GUI technology in MATLAB. By comparing simulation result curves with different parameters combination, the effective approach to optimize the performance of this system can be easily achieved.
