Seat recycling system for ejection tests

Abstract

The invention discloses a seat recycling system for ejection tests. The seat recycling system for the ejection test comprises a recycling parachute (1), a hanging device (2), a life-saving box cover (27) in a seat bucket, a parachute sleeve and a packaging rope (26), wherein the hanging device (2) is installed on a seat, the parachute sleeve is sewn on packaging cloth on the inner side of the life-saving box cover and used for packaging the recycling parachute (1), the packaging rope (26) seals the packaging cloth of the life-saving box cover to realize the packaging of the recycling parachute(1) and connected to the bottom plate of the seat bucket, and the two ends of the parachute rope of the recycling parachute (1) extend from the rears of the left and right sides of the life-saving box cover (27) and are connected with the top end of the hanging device (2). According to the invention, the recycling parachute is installed in the space on the inner side of the seat chair and under the human body, so that the eccentricity of the seat cannot be influenced, and the test state and the actual use state can be highly fitted. The system can be used by matching with various situations of ejection tests, especially high-speed ejection tests, the state of the seat after ejection tests is basically complete, and the recovery success rate of the seat is high.

Description

technical field [0001] The invention relates to the technical field of ejection tests, in particular to a seat recovery system for ejection tests. Background technique [0002] In the existing ejection test seat recovery system, the recovery umbrella is packaged in an umbrella bag, the umbrella bag is fixed on the back of the dummy, and the umbrella rope is connected with the seat. This recycling method has the following defects: the umbrella bag is fixed on the back of the dummy, which makes the dummy lean forward, which greatly affects the center of gravity of the man-chair system. In order to reduce this effect, it is necessary to reduce the packaging volume of the recovery umbrella as much as possible, so that the canopy area of ​​the recovery umbrella is small, and the speed of opening the umbrella is low, which cannot withstand the dynamic load of opening the umbrella when the person and chair are separated in the high-speed ejection test. Therefore, The existing seat...

Problems solved by technology

This recovery method has the following defects: the umbrella bag is fixed on the back of the dummy, which makes the dummy lean forward, which greatly affects the center of gravity of the man-chair system

In order to reduce this effect, it is necessary to reduce the packaging volume of the recovery umbrella as much as possible, so that the canopy area of ​​the recovery umbrella is small, and the speed of opening the umbrella is low, which cannot withstand the dynamic load of opening the umbrella when the person and chair are separated in the high-speed ejection test. Therefore, The existing seat recovery system can only recover seats for low- and medium-speed ejection tests, but cannot perform seat recovery for high-speed ejection tests, so as to realize the recycling and reuse of seats

In addition, due to the impact of the recovery system on the eccentricity of the human-chair system, it is impossible to guarantee the fit between the seat test state and the real use state
