基于灵敏度桑叶采摘机机架多目标轻量化设计
Multi-objective Lightweight Design of Mulberry Leaf Picker Frame Based on Sensitivity
摘要
Abstract
The frame is very important to the reliability of mulberry leaf picker.To improve the performance of mulberry leaf picker,it is necessary to design and optimize the structure of the frame.Firstly,the static analysis,modal analysis and sensitivity analysis of the frame were carried out.Through the analysis,the working frequency of the engine was close to the sixth order natural modal frequency of the frame of the mulberry leaf picker,which was easy to cause the frame resonance.In order to avoid resonance effects,a multi-objective optimization mathematical model was established and the optimal design scheme was obtained by using fuzzy matter-element method based on entropy weight.After optimization,the natural frequency of the mulberry leaf picker frame was not only reduced,far away from the working frequency and starting frequency of the motor,but also the mass of the frame was reduced by 9.629％and the maximum deformation was reduced by 11.927％,realizing the multi-objective optimization of the frame structure.关键词
