PREMILINARY EXPLORATION ON REALIABILITY DESIGN METHOD OFCOMPOSITE STRUCTURE IN WARSHIP

Abstract

Abstract: Reliability is one of the important indexes to measure the inherent reliability of structures. The right selection of reliability analysis and calculation method is the basis and guarantee for the reliability assessment of composite structures in warship. Working environment of composite structures for naval ships is complicated, and the discrete characteristics of its structural mechanics performance is higher than that of the traditional metal structure and the problem of structural reliability is relatively serious because of the limitations of the designing technology and the production capability. For this reason, firstly, the paper analyzes structural strength properties and its regularities of distribution of composite structures for naval vessels. Then,we pesent the method of analyzing reliability of composite structures based on stress-intensity interference model and working out reliability by safety factor method for the design of allowable values of the reference design. In the two parts, it has obvious advantages and operability in solving problems and result accuracy, which has important reference value for the development of structural fatigue reliability assessment of naval vessels.

Key words: reliability, composite structures in warship, reliability design of structure, stress-intensity interference model, safety factor method of allowable value of B reference design
