面向山地路况的农用运输车架多工况结构优化
Multi-condition structural optimization of agricultural transport vehicle frame for mountainous road conditions
摘要
Abstract
To address the issues of stress concentration and stiffness redundancy in mountain agricultural transport vehicle frames,a structural optimization method based on multi-condition analysis was proposed.Taking a certain type of frame in Fujian as the object,a finite element model was established in ANSYS Workbench,and four typical working conditions(full-load bending,extreme torsion,emergency braking,and extreme turning)were set,and the stress and deformation characteristics were analyzed.Based on topology optimization,a lightweight design was carried out with the goal of minimizing mass,constrained by volume fraction and stress.The results showed that the maximum equivalent stress of the original frame under extreme torsion was found to be 110.99 MPa,which was identified as the core condition for structural strength de-redundancy verification;after optimization,the frame mass was reduced by 15.3%,and stress concentration was significantly reduced.The effectiveness of this method in improving frame safety and lightweight was verified.关键词
