英文摘要： The multidisciplinary design optimization (MDO) computing framework for AUV is the platform to development MDO of AUV. Combined with the defects of existing MDO computing frameworks and the future trends of the overall design of AUV, the MDO computing framework for AUV oriented to cooperative design is studied.The problems of the existing computing frameworks which does not support multi-user cooperative design and the distributed parallel computing of multiple design flows are solved. The two key technologies including the design flow visual modeling method and the task scheduling method of multiple design flows are studied. The former solves the visual modeling problem of design flow with complex structure, and provides the visualized input interface for the design flow information. The latter solves the task scheduling problem of multiple design workflows with priority and timing constraints, and ensures the efficiency of parallel computing with multiple design flows. This Research can improve the level of AUV overall design and enrich the MDO theory and application.It also has reference value to the application and promotion of MDO in other engineering fields and has important theoretical significance and application value.
