Paper Title:
Effect of Dimensional Tolerance on Displacements and Stresses of Wedged-Ring Joint Structure
  Abstract

The effect of geometric clearances on the stress and deformation distributions of a wedged-ring joint structure is studied, five cases of dimensional tolerance of each contact surface, i.e., the maximum, minimum, mean of maximum and minimum, mean of maximum and mean, and mean of minimum and mean are investigated, and the probable states that the wedged-rings attach with the upper cylinder or attach with the lower cylinder radially in the assembly process are considered as well. The results of finite element numerical simulations indicate that in the design tolerance zone, the effects of geometric clearances between contact surfaces on the displacement and stress distributions of the structural components are weak. Only when the wedged-rings attach tightly with the upper cylinder or with the lower cylinder, the displacement and stress distributions in the joint of the structure occur a dramatic variation, and the assembly processing measure making the wedged-rings attaching tightly with the lower cylinder can be adopted to effectively decrease the stresses and deformations in the joint of the structure.
