The calculation method of stress sensitivity and displacement sensitivity in the optimization of the structure of thin-walled cover is analyzed. The structure analysis and the sensitivity calculation are carried out by the finite element method. The formula of sensitivity is deduced and applied to the structure of the thin-walled cover Optimization design and satisfactory results were obtained.The finite element analysis of the thin-wall cover used the plate element and the beam element.The calculation results of application examples show that the calculation methods of stress sensitivity and displacement sensitivity are accurate and reliable
