Abstract
Considering resonance observed in the loader steering wheel at idle speed,a size optimization design approach based on response surface analysis is proposed.Taking the steering wheel frame of the loaders as the research object,with its mass and natural frequency being the key optimization targets.the Spearman rank correlation coefficient was used to ascertain the sensitivity of the steering wheel frame's dimensional parameters in relation to the desired performance.Subsequently,design of experiments(DOE)were conducted by optimal space-filling design,and the response surface was fitted by Kriging method.Finally,utilizing the constructed response surface model,MOGA(multi-objective genetic algorithm)was used to optimize and determine the optimal solution.The findings reveal that the overall mass of the optimized steering wheel frame was reduced by 12.9%,and the first-order natural frequency was elevated to 97.96 Hz,significantly higher than the engine's excitation frequency range of 37.5 Hz to 50 Hz.This increase effectively avoids the sensitive frequency range that affects human hand vibration,thereby enhancing drivers'comfort during operation.Research results can provide theoretical support and reference for the optimization design of similar engineering structures.关键词
