The invention discloses a semi-active vibration reduction method and system for a lightning protection seat. According to the vibration reduction method, after it is judged that a vehicle encounters lightning, an electric locking mechanism is controlled to be unlocked, the lightning protection seat is in a suspended state after rigidly separated from the vehicle, at the moment, due to the fact that the lightning protection seat does not contact with a vehicle body, when explosion energy is transmitted to the vehicle body, the explosion energy cannot be transmitted to the lightning protection seat, and thus, non-contact vibration reduction is achieved; the seat plate of the lightning protection seat extends to automatically lift the legs of a passenger, so that the lightning protection seatcan be connected with the chassis of the vehicle. The vibration reduction system is designed on the basis of the semi-active vibration reduction method. Compared with common energy absorption design,the vibration reduction method and the vibration reduction system have the advantages of capability of fundamentally solving energy transmission, in-time vibration and good vibration reduction effect, and can guarantee the safety of people on the seat.
本发明公开了一种用于防雷座椅的半主动式减振方法及减振系统,该减振方法中,当判断出车辆遇雷后,控制电动锁紧机构解锁,防雷座椅与车辆刚性分离后,呈悬浮姿态,此时,由于防雷座椅与车体不接触,所以当爆炸能量传递到车体时,并不会传递给防雷座椅,进而实现不接触减振。与此同时,防雷座椅的座板伸长,自动将乘坐人员腿部抬起,以配合防雷座椅与车辆的底盘相接。上述减振系统,是基于上述的半主动式减振方法设计的,上述减振方法和减振系统,相比于普通的吸能设计,能够从根源上解决能量传递的问题,不仅避振及时,而且减振效果好,进而保证座椅上人员安全。
