| Abstract:In order to reduce efficiently the stress level, a five-parameter non-circular clearance hole of the labyrinth disk was
taken as the research object. Aiming at the dimension tolerance design of non-circular hole, the response surface functions of the
stresses near the hole were built to conduct sensitivity analysis for the design parameters using the Monte Carlo Simulation method, and
the design variables which need appending tolerances were determined. The influences of the most important design dimension tolerances
zone of the non-circular hole on stress distribution and coordination of the hole edge were discussed, and the selection of dimension
tolerance of the non-circular hole that meets the requirement of both strength and the assembly specifications of ANSI is determined. |
