Abstract

The invention discloses an ultralow-frequency angular vibration control system and an application method thereof. The system comprises a mounting frame and an upper cover plate, multiple steel wire rope vibration isolation units are connected between the upper cover plate and the mounting frame, and a distance in the height direction is formed between the upper cover plate and a bottom plate of the mounting frame. A vertical impact resistance device is fixed in each steel wire rope vibration isolation unit, vibration isolation and impact resistance are integrated, multiple pairs of longitudinal and transverse air bag impact resistance devices are fixed to the corners of an inner cavity of the mounting frame, and impact resistance protection in the transverse direction, the longitudinal direction and the attitude angle direction is achieved. Multiple permanent magnets are fixed to the inner wall of the mounting frame, the same permanent magnets are also fixed to the lower surface of theupper cover plate, when the upper cover plate is fixed above the mounting frame, multiple pairs of parallel and opposite permanent magnet sets are formed between the upper cover plate and the mounting frame, negative rigidity is provided for offsetting positive rigidity provided by the steel wire rope vibration isolation units, and the multidirectional low-rigidity characteristic is achieved. Therefore, the system not only has good vibration control performance, but also has excellent impact resistance.

Description

technical field

[0001] The invention relates to a vibration control and shock resistance system, in particular to an ultra-low frequency angular vibration control system and a vibration control method thereof. Background technique

[0002] During the mobile operation of laser defense weapons, the operation of auxiliary equipment and road excitation will not only be directly transmitted to the laser transmitter, but also excite the natural frequency of the delivery system itself, causing torsional vibration of precision equipment such as laser defense weapons, which significantly reduces the laser power. The strike accuracy of the weapon. More importantly, the road surface excitation and the vibration of the carrier equipment excited by it contain low-frequency components, and the amplitude of the low-frequency components is relatively large, which has a more obvious impact on laser weapons. However, due to the contradiction between the support capacity and the support stabi...
