Parameter Optimization of Torque Bar in Folding Wing

Zhen Wenqiang;Ji Yongqiang;Shi Yunguo;Institute of Systems Engineering,China Academy of Engineering Physics;  
The influences of shear stress distribution in different section shapes and length-width rates of the square section on the bar were analyzed herein.The results show that increasing the length-width rate of the section can decrease the critical length of bar efficiently,while the elastic energy that the bar created remaines the same.Based on the dynamics model of the deploying progresses of the folding-wing and constraints from the wing,a optimization model of the torque bar was built,where the target function was the total mass of the bars.Using Isight and MATLAB software,the length,the width,the height and the number of bar groups were optimized in the program.The optimized parameters may increase the structure efficiency and shorten the size of the bar,which may benefit the engineering designs.
