  • To reasonably design and control blade-tip clearance, the nonlinear and dynamic probabilistic analysis of disk radial deformation was studied based on finite element model (FEM) and response surface method (RSM). Through deterministic analysis of disk deformation considering material nolinear and loads dynamic, the disk radial deformation change with time and the maximum value of disk deformation were gained. It was available to the distribution feature of disk deformation, the failure number and reliability degrees under different radial deformation preset value δ, the limit values of random parameters under different reliabilities and the sensitivities of random parameters influencing the disk radial deformation.
