Researching on Testing Method for Dynamic Property of Buffer Packaging

The fragility of products and the dynamic characteristic of packaging material are important points in packaging dynamics. An intelligent testing instrument has been designed, which uses W78E52B SCM as CPU, and 2 axial mounted acceleration sensors as 3-Dimensional Acceleration sensor. The analogue output of the sensor is acquired by 16-bit ADC ADS8341, and transferred into inner memory. Through USB port data and parameters are transferred between PC and the device. With the input of dropping height and delay, the time of data sampling and logging is generated. Finally through PC software reading and analyze of the data is performed.
