| 摘 要： | 研究了气流偏角变化条件下,复合材料壁板颤振分析及其优化设计问题.采用考虑气流偏角影响的一阶活塞理论和Von-Kannan大变形理论建立了复合材料壁板颤振方程.通过模拟退火优化方法,对不同气流偏角下的壁板颤振速度进行了计算.以偏航壁板颤振速度为目标函数进行了壁板结构的优化设计.分析结果表明:采用所提出的偏航壁板颤振速度,能更好地分析复合材料壁板在机动飞行时的稳定性;通过铺层方式优化设计,能明显提高偏航壁板颤振速度,并较好地解决现有壁板颤振优化设计带来的最优铺层方式的选择问题.给出的算例验证了方法的有效性.

| Abstract: | Considering variations in flow yaw angle,the problems of flutter analysis and optimization design of a laminated composite panel are investigated.Accounting for the effects of yaw flow angle,a finite element representation of the composite panel flutter is established by using the Von-Karman large deflection plate theory and the first-order piston aerodynamics.The panel flutter speeds under different yaw flow angles are obtained by means of a simulated annealing optimization algorithm.Taking panel flutter s... |
