Hydraulic Manifold Intelligent Optimization Design System - The Model Database And System Integration

Integrated hydraulic Manifold system (IHMS) offers many advantages including reduced connectors, size and complexity, and enhanced flexibility for installation and maintenance. It provides a cleaner, leak-free, less vibrant and more reliable solution to difficult machine control system problems. So it is widely used in such fields as mechanism, metallurgy, forging, aviation, space flight, shipping and so on. As the key component of IHS, hydraulic manifold block (HMB) is still difficult to be designed in factories nowadays depending on the experience and imagination of workers.Aiming at the problem of how to attain the optimum integrated layout and connection schemes automatically, a HMB Design system was developed by Dut hydraulic staff room, using Intelligent Optimization Algorithms such as Genetic Algorithm and Simulated Annealing Algorithm, which has some disadvantages including the structure and content of the component library, integration of each module, the control on design process and man-machine interaction. Based on the research mentioned above, a new HMB design system is developed in this paper to perfect and enhance the old system, which solves the difficult problem of HMB automatic design relatively drastically.Summarizing the research findings at home and abroad, it is pointed out that the core of HMB design is the problem of automatic design of integrated layout and connection schemes. On the basis of summarizing the structural features of HMB and rules of its design and manufacture and analyzing the spatial relationship in 3D layout of HMB, the optimization objects and constraints are put forward. Then the mathematic model of HMB design is represented.On the basis of analyzing the attribute and structure of hydraulic components produced by different factory and abstracting its design information, hydraulic component database and graphics library are established according to scientific classification in this paper, which provide great support for the intelligent optimized design of HMB.A HMB intelligent optimal design system based on MDT software is developed by integrating the algorithm of six typical parts involved in HMB design, using Visual C++, ObjectARX development toolkit and MCAD API. In the end, a typical IHS is designed using the system and the satisfying results have testified the practicability of this system.
