摘要
依据H构型无人机总体设计要求,对复合材料机臂进行有限元分析与优化。根据无人机机臂的承载特点实现复合材料机臂的初步设计,建立机臂有限元优化模型;以提升机臂结构性能为优化目标,结合有限元计算结果和实际制作工艺,确定机臂优化结构。优化后的结果表明:整体满足设计要求且力学性能大幅提升。
According to the overall design requirements of the H-configuration UAV,the finite element analysis and optimization of the composite arms are carried out.Based on the bearing characteristics of the drone arm,the preliminary design of the composite arm is worked out and the finite element optimization model of the machine arm is established.With the improvement of the arm structure performance as the optimization goal,the arm optimization structure is finalized by combining the finite element calculation results and the actual manufacturing process.The optimized results show that the overall design requirements are met and the mechanical properties are significantly improved.
