Abstract

Abstract

For a military vehicle, an unbuffered platform airdrop test was performed at a height of 1 m. And a seat-crew model was built. The impact signals at the seat installation point were obtained by the test. The obtained signals were used as the input of the simulation model, and the reliability of the model was verified by comparing the test and simulation data. Based on the aeronautical engineering related research, a weight evaluation index named weighted injury criteria (WIC) was presented by normalizing each key damage index. The influence of two posture parameters, namely the crew’s supine angle and the angle between the calf and the thigh, on the crew’s injury was studied. With the WIC as the optimization target, the genetic algorithm was used to obtain the optimized parameters. The study finds that to restrain the motion of the crew’s calf can reduce his overall injury response. The optimal posture of the crew against the landing impact is the supine angle range from 47° to 56°, and the angle between the upper and lower legs is from 62° to 68°.
