It further include traction mechanism, the traction mechanism top is connected to lifting mechanism, the hook of lower part joint test vehicle,
When rising, traction mechanism can simulate parachute lanyard, can give test vehicle downward acceleration in release test vehicle
Degree after test is completed, restores to the original state, reusable.
It further include energy absorber, the energy absorber is located at test vehicle bottom, provides and delays to vehicle when vehicle is bottomed out
The effect of energy is suctioned, damage of the impact to test vehicle and testing dummy is reduced.
The lifting mechanism includes lifting bracket and lifting motor, and the lifting bracket can stablize support test vehicle, is lifted
When lifting motor can give starting loop under control to simulate Parachute Opening from air drag to test vehicle generate to
On acceleration.
The data acquisition instrument includes internal motion camera, acceleration transducer and external high-speed camera.
Equipped with multiple biomechanical response sensors on the testing dummy.
The occupant injury evaluation criterion of complete set is set, provides foundation for test evaluation.
The present invention proposes that a kind of ground simulation load person drops from the air vehicle airdrop test and its device, simulates vehicle of dropping from the air under different operating conditions
Landing mission, be according to the shock resistance for examining airborne vehicle with the lesion assessment of parachutist's safety evaluatio and vehicle.By
In its economy, flexibility and repeatability, the effective means for studying the impact resistance of airborne vehicle can be used as.
Simulator proposed by the present invention can effectively simulate effect of the parachute to body construction in real vehicle airdrop test
The severe impact of car body is faced when power and landing, and is not restricted by factors such as weather, test flexibility is more preferable, simultaneously
The biomechanical response of passenger and the structural response of car body can accurately be acquired.For comparing real vehicle airdrop test, drop
Low experimentation cost, shortens the test period, improves the feasibility of acquisition occupant's biomechanical data and car body response data.
