| Abstract: | The body deceleration in frontal crash can be simplified to become an equivalent dual-trapezoidal wave. Using this method to analyze the waveform characteristics has important application value in structure optimization. In this paper, equivalent dual-trapezoidal wave is regarded as the design object. Waveform parameters are analyzed in order to select the optimal scheme. |
