摘　　要：在齿轮传动系统的协同设计中,存在任务间耦合关系复杂、返工现象严重、设计流程混乱的问题,针对这一问题,提出了一种基于模糊设计结构矩阵(FDSM)的全局局部两级任务规划方法。首先,根据任务分解层次结构对设计任务进行了分解,依据设计任务间的输入输出关系构建了FDSM,通过对FDSM的行列变换完成了对耦合设计任务的识别与非耦合设计任务的规划,实现了全局规划;其次,引入了模糊耦合度量化设计任务间的耦合程度,计算了耦合集内各任务的输入输出量,完成了耦合任务集的解耦,实现了局部规划;最后,以齿轮传动系统协同设计为例,阐述了整个规划过程,并对所提出的方法进行了验证。研究结果表明:规划后FDSM的复杂程度降低了35.32%,减少了设计迭代次数;实现了并行设计任务集的自动识别,优化了设计任务执行次序,缩短了设计时间,可以为协同设计任务分配提供参考。The complex coupling relationship among tasks,serious rework,and chaotic design process existed in the collaborative design of gear transmission systems,in order to solve the problems,a global-local two-level task planning method based on the fussy design structure matrix(FDSM)was proposed.First,the design tasks were decomposed according to the hierarchical structure of task decomposition,the FDSM was modeled in the light of the input-output relationship between design tasks.The coupled design tasks were identified and the uncoupled design tasks were planned through the transformation of FDSM s ranks to achieve global planning.Secondly,the fuzzy coupling degree was introduced to quantify the strength of coupling between design tasks,and the inputs and outputs of each task in the coupling set were calculated to complete the coupling decoupling of task sets and enable local planning.Finally,taking the collaborative design of gear transmission system as an example,the whole planning process was explained,and the feasibility of the proposed method was verified.The results show that the complexity of FDSM is reduced by 35.32%and the number of design iterations is reduced.The automatic recognition of concurrent design task sets is realized,and the execution order of design tasks is optimized,the design time is shortened,and the basis for collaborative design task allocation is provided.
