玉米运输侧翻式铝合金半挂车车架多工况力学性能分析
Multi-condition mechanical performance analysis of corn transport side-over aluminum alloy semi-trailer frame
摘要
Abstract
To achieve lightweight design and high reliability for corn transportation equipment,a steel-aluminum hybrid side-dump aluminum alloy semi-trailer frame was developed in this study.A three-dimensional geometric model of the frame was established using SolidWorks,and mesh generation,material properties,and connection definitions were completed in HyperMesh.Static analyses under typical working conditions—including bending,torsion,turning,braking,and unloading—were carried out in OptiStruct,along with a free-modal analysis.The results showed that the maximum equivalent stress and maximum deflection of the frame under bending,turning,and braking conditions all meet the design requirements.Under the torsion condition,the maximum displacement of the rear longitudinal beam reaches 15.23 mm,which was slightly higher than the deflection limit of 13 mm.The unloading condition was identified as the most unfavorable scenario,where the maximum equivalent stress at the front hydraulic cylinder support was 452.60 MPa,still below the material's yield strength.The first six natural frequencies of the frame range from 5.05 to 29.41 Hz,all above the asphalt road incentive frequency range,the structure does not resonate.关键词
