Prediction of Probabilistic Distribution of a Loudspeaker`s Performance Due to Manufacturing Tolerances by Performance Moment Integration Method Kang, Byung-su; Back, Jong Hyun; Kim, Dong-Hun;
This paper introduces a performance integration method to predict variation characteristic of a performance function of electromagnetic machines or devices due to manufacturing tolerances. A normalized performance function space and a hybrid mean value technique are adapted to effectively predict mean and variance, which can identify probabilistic distribution of the performance function. To verify the effectiveness and accuracy of the proposed method, a mathematical problem and a loudspeaker model are tested, and numerical results are compared with those of existing methods such as Monte Carlo simulation and univariate dimension reduction method.
