A test method and test bench for knee module impacting dashboard were proposed and designed, to reproduce the contact of the dummy leg with dashboard in real vehicle crash. The collision process between the knee and the dashboard in the car was studied pertinently, and the knee invasion curve on the dashboard was obtained by the high-speed camera dynamic displacement calculation method, which was interpolated and integrated to obtain the relationship between the injury index of the dummy leg and the amount of knee intrusion on the dashboard, to directly reflect and verify the collision protection performance of the dashboard to the leg.
