Finite Element Analysis of the Hull Structure based on Knowledge-Based Engineering
Abstract:To solve the problem of long cycle and inefficiency of traditional finite element analysis of hull structure .The idea of Knowledge-Based Engineering is applied to finite element analysis in this paper that propose a new method of finite element analysis based on Knowledge-Based Engineering of hull structure. It depends on establishing designing knowledge base and checking knowledge base. According to the results of finite element analysis, the checking knowledge base judge and modify them to meet the design requirements. The process of realization of this method is introduced by example. The proposed method is shown to effectively improve the efficiency of finite element analysis.
