摘要
为了研究飞机除冰车臂架性能,利用三维实体软件和有限元分析软件建立了臂架的数值仿真模型,并对除冰车臂架强度和刚度进行有限元分析,研究其在最危险作业工况下的应力分布情况、变形情况。仿真结果表明,除冰车结构件部分的整体应力均小于材料许用应力值,分析出臂架结构中应力集中区域,对臂架结构优化及生产制作有重要的参考价值。
In order to study the performance of aireraft deicing vehicle's arm,established numerical simulation model of the arm by three-dimensional software and finite element analysis software,study on the strength and stiffness of aircraft deicing vehicle's arm, and researched the distribution of stress and deformation under the most dangerous condition.The resuhs showed that the stress is all less than the allowable stress values except the deicing vehicle structure, and found the stress eoncentration areas of the arm structure. It has important gqiding significance to the optimization and manufacturing production of the arm structnre.
