| The strong coupling effect, which results from the external components layout design and internal flow paths connection design, is a crucial issue to prevent the achievement of automatic design in Hydraulic Manifold Block(HMB), and the problem of combinatorial explosion arises easily by simple optimization algorithm to solve the HMB design problem. In component layout design, it is difficult to meet the mounting and debugging requirement of components by the optimization algorithm. In path design, the existence of technical hole and the structural particularity of side hole increase the complexity of coding for optimization algorithms. In this paper, using knowledge-based method, subsequent path design is taken into consideration by combination of component layout design and path design to realize the rapid design of HMB. The main work is as follows:The component layout design method is presented based on core component first. The component layout rule base is established and the component layout decision tree generate mechanism is formulated. The component grouping strategy is proposed on the basis of core component, which improves the efficiency of decision-making, reasoning and reuse of rule in the component layout process.And then a rapid design method for multi-port path is presented which can support the paths include side port of cartridge valve. Since the design constraints for key paths were guaranteed by component layout design, the design efficiency of the above paths can be improved by this method.Then an adaptive update method of dynamic path is proposed. Obstacle avoidance and optimization of path can be realized by using MAZE algorithm. The path code is converted to temporary body by using feature-reconstructing technology, which achieves adaptive update of topology structure with partial conflict feature.At last, by taking a typical hydraulic system as an example, the result verifies the feasibility and effectiveness of the proposed design method for HMB. |
