Abstract

This paper introduces a probabilistic analysis method in order to analyze the effect of manufacturing tolerance on induction motor performance occurring in massive production. The univariate dimension reduction method is adapted to predict probabilistic characteristics of a performance function due to certain probabilistic distributions of design variables. Moreover, the sensitivity information on mean and variance of the performance function is estimated, and then the effect of randomness of individual design variables on the probability performance function is analyzed. The effectiveness and accuracy of the method is investigated with a mathematical model and an induction motor.

본 논문에서는 전동기 제작과정에서 발생하는 제작공차가 유도전동기 성능에 미치는 영향력을 분석하기 위하여 확률론적 해석기법을 도입하였다. 단변수 차원 감소법을 사용하여 특정한 확률분포를 갖는 설계변수에 의해 발생하는 성능함수의 확률분포 특성을 예측하였다. 또한 확률성능함수의 평균과 분산의 민감도 정보를 도출함으로써 개별 설계변수의 임의성이 확률성능함수의 분포에 미치는 영향력을 분석하였다. 제안된 기법은 간단한 수학예제와 유도전동기 모델에 적용하여 그 효율성과 정밀도를 검증하였다.
