Adaptive Semiactive Bumper for Aircraft

摘要

摘要: 为解决传统飞行器着陆缓冲系统刚度和阻尼不可调节的问题,设计了磁流变变阻尼器件和磁流变弹性体变刚度单元并联的半主动控制缓冲器,建立了变刚度变阻尼控制模型,提出了基于能量守恒原理的磁流变自适应变刚度变阻尼控制策略.飞行器着陆过程缓冲控制的仿真实验结果表明:采用磁流变自适应变刚度变阻尼半主动控制技术后,飞行器受到的冲击能量在整个时间历程的分布更为合理,最大冲击载荷下降17%左右.

Abstract: To avoid the limitation of traditional aircraft bumpers that their stiffness and damping factors are not adjustable,a new bumper was designed.It consists of a magnetorheological (MR) damper with variable damping factors and a magnetorheological elastomer (MRE) with variable rigidity,and the two parts are connected in parallel.The control models of the two parts were derived.An adaptive variable stiffness and damping control strategy based on the energy conservation principle was proposed.Simulation results showed that the bumper made the impact energy distribute more evenly,and reduced the peak impact load by about 17%.
