摘要： A method for impact test on a lower abdomen of a vehicle crash test dummy includes: controlling an arc-shaped hammer head to impact a lower abdomen of a preset dummy at a preset speed; obtaining displacements from a displacement sensor, wherein the displacements are generated by the lower abdomen of the preset dummy and the arc-shaped hammer head during the impact; obtaining a pressure from a pressure sensor, wherein the pressure is borne by the lower abdomen of the preset dummy during the impact; and determining, based on the displacements and the pressure, whether the preset dummy satisfies a biological simulation standard. The method is capable of testing whether the current dummy satisfies the biological simulation standard, so as to ensure the accuracy of test data in subsequent vehicle crash tests using the dummy.
