Notes:
The effect of geometric clearances on the stress and deformation distributions of awedged-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, andmean of minimum and mean are investigated, and the probable states that the wedged-rings attachwith the upper cylinder or attach with the lower cylinder radially in the assembly process areconsidered as well. The results of finite element numerical simulations indicate that in the designtolerance zone, the effects of geometric clearances between contact surfaces on the displacementand stress distributions of the structural components are weak. Only when the wedged-rings attachtightly with the upper cylinder or with the lower cylinder, the displacement and stress distributionsin the joint of the structure occur a dramatic variation, and the assembly processing measure makingthe wedged-rings attaching tightly with the lower cylinder can be adopted to effectively decreasethe stresses and deformations in the joint of the structure
