A new intelligent method of transmission scheme for aero-engine accessory drive system with parallel shafts system is investigated,Considering the influence of both attachment interference and the design criterion of transmission,the drive system of attachments is regarded as a single-input and multi-output black box. By using the knowledge of graph theory,the adjacency matrix is defined,then referring to TSP(Traveling Salesman Problem),the weight of the attachment node path can be determined except the pos...
