Research And Application Of Waveform Generator For Deceleration Sled

Taking the waveform generator of the deceleration sled as the object of study,this paper studies the influence of the length of the energy absorbing steel plate and the initial speed of the deceleration sled on the acceleration curve of the energy absorbing steel plate in the waveform generator.On this basis,taking the acceleration curve of seat dynamic test as the target curve,the real car crash test and computer simulation test are carried out.The acceleration curves obtained from the tests are in agreement with the target acceleration curve.It is obvious that the research on waveform generator is effective,and the research results can reduce the car crash test.Test cost and shorten R&D time.
