Abstract In this paper, the stiffness of carbon fiber composite sliding door was studied by means of finite element simulation and test. The calculated and measured deformations of sliding door under aerodynamic loads were compared and analyzed. The results showed that the deformation of the composite door under the two methods of test and simulation showed a linear trend with the increase of load. The displacement values obtained by the two methods were very similar. For example, the maximum and minimum displacement actual measured value were 13.98 mm and 2.26 mm, with an error of 14.2%, and the theoretical calculation values were 12 mm and 2.19 mm, with an error of 3.1%. The rationality of simulation analysis method and test method was verified. The stiffness of the door was significantly affected by the height of the inner and outer panels at different locations. The reason is that the height of the door affects the flexural capacity of the door, and the door is mainly subjected to the out-of-plane load. Therefore, the stiffness of the door depends on its flexural capacity.
