基于相似应力特征分布的挖掘机动臂应力预测模型
New Stress Prediction Model of Excavator Boom Based on Distribution of Similar Stress Characteristics
摘要
Abstract
The low universality exists in the neural network prediction model of the excavator boom structure stress.This paper presents a method which is used to classify the similar characteristic stress of the boom,establishes the neural network prediction model,takes small and medium-sized excavator hydraulic cylinder with double gooseneck boom as an example,uses the stratified sampling method to obtain the analysis samples,and establishes the similar stress feature classification model to classify the sample,then establishes the stress prediction models to achieve more rapid and accurate prediction and improve the efficiency of the boom structure optimization.关键词
