|
摘要
为了抑制直升机飞行过程中的机身振动,引入磁流变半主动控制技术和立方结构Stewart平台,提出一种应用磁流变阻尼器的直升机主减隔振平台,确定了磁流变阻尼器和隔振平台结构参数,建立了隔振平台的动力学仿真模型,基于等效天棚阻尼开关控制和等效天棚阻尼模糊控制策略进行仿真分析。研究结果表明:隔振平台满足设计要求,能有效抑制某型直升机旋翼/主减系统一阶通过频率23.9Hz的振动载荷向机身的传递,在等效天棚阻尼模糊控制下,隔振效率能够达到80%,同时在高频区也具有一定的隔振效果。
In order to restrain vibration of fuselage during the flight, the vibration isolation platform for the helicopter gearbox is designed with magnetorheological semi-active control technology and cubic structure of Stewart. The parameters of shear-valve mode MR damper and platform are designed, and the dynamic simulation model of vibration isolation platform is established and conducted with the equivalent sky-hook switch control and equivalent sky-hook fuzzy control. It shows that the vibration load of 23.9 Hz which is the first order passing frequency of a helicopter gearbox/rotor system is effectively inhibited by the vibration isolation platform, the vibration isolation efficiency is achieved 80% with equivalent sky-hook fuzzy control, and the vibration isolation platform can restrain vibration in high frequency region.
