In this study, the reliability of the traditional equivalent drop theory for transport packaging was experimentally evaluated, and a new physical model that considers the factor of friction was proposed. Using this new model, mathematical shock response equations of a shock test and a test at free‐fall were deduced. In addition, a correcting condition was reached. To let the equivalent free‐fall height be exactly equivalent, a new friction equivalent drop theory was proposed. This theory not only significantly reduces experimental errors and improves the accuracy of equivalent experiments but also provides a new theoretical basis for experimental analysis of structural cushioning materials.
