Abstract：In order to analyze dynamic stress response of cantilever beam under the excitation of rectangular acceleration pulse, relationship between maximum stress at the cantilevered end and rectangular acceleration pulse amplitude was deduced, which shows that the maximum stress increases with increasing of the acceleration amplitude but approaches the limit given the velocity change for acceleration pulse is constant. Finally, analytical method was verified by finite element results, meanwhile 2-order vibration modes are enough to give a good estimation for the stress response of cantilever, which can provide theoretical foundation for the electronic product with cantilever beam type when honeycomb paperboard used as cushioning material.
