| Abstract: | The geometric parameters of laminated plates of composite material are usually random due to the effect of various indeterminiate factors in engineering structure. The study of the sensitivity of random parameter laminated plates and the analysis of the optimum design of parameters play on important role in the right estimation of the reliability of construction design. This article infers the calculation formula for responding sensitivity of anti symmetrically laminated plates by using random perturbation law, studies the responding sensitivity and the optimum design of random paramters of antisymmetrically laminated plates, and calculates the best angle of arranging lamina tion by using the mesh law. |

| Keywords: | laminated plates random parameters antisymmetrically laminated plates responding analysis sensitivity analysis design optimization |
