Method for quantitatively evaluating automobile head-on collision waveform strength

The invention provides a method for quantitatively evaluating automobile head-on collision waveform strength. The method comprises the steps of: establishing a model and a differential equation, obtaining and processing automobile body acceleration data, obtaining a solution of the differential equation, and obtaining an x-direction acceleration severity curve ASP and an acceleration severity index ASI of passengers in an automobile. The invention discloses a method for quantitatively evaluating automobile head-on collision waveform strength. Acceleration data of a vehicle body can be collected and processed; model establishment and calculation are carried out, the automobile head-on collision waveform intensity is directly quantified without depending on an existing method for carrying out evaluation by depending on a dummy damage value in an automobile in collision, quantitative evaluation is provided for the safety performance of an automobile body structure in the early stage of automobile development, an
