多可信度数据融合的轴系临界转速预测
Critical Speed Prediction of Shaft Systems Based on Multi-credibility Data Fusion
摘要
Abstract
In the optimization design of rotor system structure,it is crucial to control the critical speed of the shaft system.To address the issues of limited experimental data and low simulation accuracy in construction of critical speed prediction models,a multi-credibility data fusion modeling method based on input dimension enhancement is proposed.This method incorporates simulation results as new design variables into the prediction model construction,and suppresses the interference of noise errors in the initial experimental samples by reducing the influence weight of the initial design variables.Compared to the collaborative Kriging method,this method is suitable for situations in which the high reliability samples are not very few but include initial errors,and the accuracy of low reliability samples is not high.By comparing the prediction accuracy of different models,the effectiveness of this method in improving model prediction stability and global accuracy is demonstrated.This study provides a new model optimization approach for solving design optimization problems in engineering practice.关键词
