An Aircraft Tooling Cooperative Design Model Based onNeuron-Endocrine-Immunity Working Principle
As restricted by airplane R&D circle,aircraft tooling design is desired to comply withairplane product design and subsequent portions.However,cooperative design for aircraft tooling,especially large-sized one,is difficult and the reasons are as follows: ①The quantity for Aircrafttooling parts is enormously large,the size is large,and the structure is complex.②Tooling designprocedure is complicated with many portions to be coordinated.③Airplane product amendments arefrequent and hard to trace.Aircraft tooling design tends to proceed without effective mechanism toevaluate and optimize manufacturing process,scheduling and etc.With these difficulties considered,an aircraft tooling cooperative design model based on Neuron-Endocrine-Immunity workingprinciple is presented in this paper.Resorting to shared chemical information molecules,Neuron-Endocrine-Immunity system forms an extensive and complicated regulating network whichregulates all cells and tissues in human body.Referring to this principle,aircraft tooling design systeminvolves controller and controlled objects.With adaptive and self-organized tooling designprocedure,rapid adjustment or reconfiguration can be realized.Meanwhile,the feasibility andvalidity of adjusting task plans and tooling design schedules are ensured.To implement this model,amulti-agent-based framework for aircraft tooling cooperative design is proposed.This frameworkincorporates PDM and united structure for effective collaboration in terms of unified data sharing,convenient tool wrapping and decentralized control.A pilot system has been developed and testifiedin an aircraft manufacturing enterprise,thus lessening repetitive modifying workload,ensuring designquality and project schedule.
