Abstract:Virtual test techniques have been more and more widely utilized in the aerospace field,especially about multidisciplinary coupling simulation. However,the study on reliability evaluating tool has not been paid enough attention to in virtual test. In consideration of the engineering requirement during test analyzing phase,we have designed and implemented a reliability evaluating tool,which includes functional modules like evaluating-objects management,evaluating-experts management,index-system construction. Moreover,it offers interfaces to virtual test and physical test databases,which effectively helps the contrast work between the two tests,standardizes the analyzing flow and content of virtual test,and highlights the work efficiency.
