Anti-vibration and anti-shock system for armored vehicle seats

Abstract

The invention discloses a vibration damping and impact resisting system for an armored vehicle seat and belongs to the field of armored vehicles. The vibration damping and impact resisting system comprises a vibration control loop and an impact control loop; the vibration control loop comprises a passive vibration isolation component, a main actuator, a first controller, a first power amplifier and acceleration sensors; the passive vibration isolation component and the main actuator are mounted between a cushion position of a seat and an intermediate mass block; the acceleration sensors are mounted on the cushion position of the seat, the bottom of the seat and a chassis of a vehicle; the impact control loop includes an adjustable damper, a second controller, a second power amplifier, a displacement sensor and an impact sensor; the adjustable damper is installed between the intermediate mass block and the bottom of the seat, the displacement sensor is installed at the bottom of the seat, and the impact sensor is installed on the chassis of the vehicle. The problem that low frequency vibration cannot be effectively controlled by means of traditional vibration isolation means is solved; the effects of effectively controlling the low frequency vibration and improving the impact resistance are achieved.

Description

technical field

[0001] Embodiments of the present invention relate to the field of armored vehicles, and in particular, to a vibration reduction and shock resistance system for an armored vehicle seat. Background technique

[0002] Studies have shown that 4Hz to 8Hz is the sensitive area of ​​the human body, and some organs of the human body will resonate in this frequency band. The vibration characteristics of armored vehicles that often drive on severely uneven roads are low frequency and high intensity. In order to improve the riding experience of the personnel in the armored vehicle and ensure a good combat state, it is necessary to effectively control the vibration in the 4Hz to 8Hz frequency band.

[0003] Traditional vibration control methods generally use springs, wire ropes, rubber, polyurethane and airbag vibration isolators, etc., which cannot provide effective vibration isolation while meeting the requirements of engineering practice. SUMMARY OF THE INVENTION ...
