Abstract:The shock resistance ability of marine equipments should be determined during the design and optimization phases of ship systems. Considering the various stochastic factors affecting shock response of equipments, the shock resistance ability is of randomness. In this paper the analysis method to obtain shock resistance ability is researched based on reliability theory. The shock response prediction model of equipments was established by neural network algorithm. Taking typical marine equipment as research object, the statistical characteristics of shock resistance ability was studied utilizing Monte-Carlo Method. The analysis method and results in this paper can be reference for ship system shock resistance design and assessment.
