Abstract:

Aero?engine usually contains a large number of pipes, the arrangement sequence of these pipes has a certain impact on the overall layout effect of the system. In order to reduce the degree of cross layout of multiple pipes, the evaluation method of pipe disassembly complexity was designed based on product assembly and disassembly, a Discrete Chicken Swarm Optimization (DCSO) algorithm was used to solve the pipe layout sequence planning. First, a calculation method of pipe disassembly complexity was proposed to evaluate the complexity of pipe system layout scheme. Next, the pipe was pre?planned by A* algorithm. Then, an obstacle avoidance algorithm was designed based on engineering rules to adjust the pipe. Finally, taking the pipe length and disassembly complexity as the optimization objectives, the pipe layout sequence was optimized based on DCSO, and the feasibility of the proposed method was verified by a layout example.

Key words: Pipe layout, Layout sequence, Disassembly complexity, DCSO, Obstacle avoidance algorithm

摘要:

航空发动机内部管路数量众多,这些管路的排布顺序对系统整体敷设效果具有一定的影响。为了减少多管交叉敷设程度,借鉴产品装配拆卸思路,设计管路拆卸复杂度评价方法,采用一种离散型鸡群优化算法(Discrete Chicken Swarm Optimization,DCSO)求解管路敷设顺序规划。首先,提出了一种管路拆卸复杂度的计算方法,进而评价了管路系统敷设方案的复杂程度。其次,通过A*算法对管路进行了预规划。然后,基于工程规则设计了一种绕障算法对管路进行了调整。最后,以管路长度和拆卸复杂度为优化目标,基于DCSO算法对管路敷设顺序进行优化,并通过敷设算例验证了所提方法的可行性。
