Summary:The invention discloses an optimization design method suitable for a multi-material multi-thickness structure, which comprises the following steps: 1) determining a design variable and a horizontal value and a response optimization target thereof according to a to-be-optimized multi-material multi-thickness structure; 2) designing an orthogonal experiment to perform simulation calculation and obtain a corresponding response data matrix; 3) calculating the signal-to-noise ratio of the response; 4) performing normalization processing on each index sequence; 5) obtaining a comparison sequence and calculating a grey correlation coefficient matrix; 6) calculating to obtain a grey correlation degree sequence; 7) performing variance analysis on the grey correlation degree sequence to obtain significant influence variables and quantify the contribution rate of each variable to response; and 8) determining an optimal parameter combination according to the determined factor level effect table so as to realize multi-obj
