In view of the problems existing in the current logistics transportation industry, such as long transportation distance, long time and large material flow. In order to effectively reduce the damage rate and transportation cost of packaging during transportation, virtual instruments are used as the data acquisition and processing platform, DY-2 impact testing machine is used as the platform for drop impact test, and a data acquisition system for drop impact test is built through multiple sensors, acquisition cards, adapters and other experimental equipment. The purpose is to study the cushioning effect and energy absorption effect of packaging materials through drop tests at different heights and thicknesses. The acceleration-stress curve is drawn through the collected data, and the energy absorption effect of packaging materials EPS is obtained through the waveform and trend of the curve. Through the method of controlling variables, after many drop impact tests, we find that the buffering characteristic curve of EPS is consistent with the classical packaging impact theory. The experimental results show that the data collection and processing methods are very standardized and accurate, which provides an important scientific basis for the design of buffer packaging.
