摘要

建立了无人机折叠尾翼展开机构的动力学模型,计算得到折叠尾翼展开的运动规律。根据折叠尾翼展开机构的设计要求及扭簧的设计准则,建立驱动扭簧参数的优化模型。采用模拟退火算法,用Visual Basic语言编制计算程序求解得到扭簧的优化参数。建立了折叠尾翼的有限元模型,针对优化前后的扭簧参数分别进行了数值模拟计算,结果表明:优化后的参数能够让折叠尾翼在满足设计要求的时间内展开到位,而冲击载荷只有原方案的23.2%。

Abstract

Establish the dynamic model of the folding empennage mechanism,the folding empennage unfolded motion law was obtained . According to design requirements of empennage mechanism and design criteria of torsion spring , the optimization model of the driving torsion spring parameters was established. Using Simulated Annealing Algorithm(SAA), the optimal parameters of torsion spring is obtained by computer program using Visual Basic. The finite element model of folding empennage mechanism was established, the numerical simulation of original and optimized design parameters were carried out . Simulation results show that the impact load of the optimized design decreased by 23.2% with the empennage unfolded time meeting the design requirement.
