Abstract: Stimulant design by using CAE is an effective method for cooking pressure vessel design, throught the stimulant design, high-stress zone can be forecasted and the design cost can be saved. The paper simulated an cooking pressure vessel by using the finite element analysis(FEA) method based on theoretic analysis, verified the structural intensity, validated its scientificity and rationality design method, and put forward the mending measure of dangerous zone, and optimized the structurald esign.

Key words: food, cooking pressure vessel, finite element analysis (FEA), simulate design
