１引言机电产品在运输过程中 ,由于包装不当而造成的损失是很大的 ,其主要原因是运输过程中的跌落与振动。运输过程中的冲击或振动通过包装箱传递给产品的动态力、加速度、速度、位移 ,不但是产品遭破坏的主要原因 ,也是缓冲包装设计的主要依据。研究包装件在冲击、振动外力作
1 Introduction Mechanical and electrical products in the transport process, due to improper packaging caused by a great loss, the main reason is the transport process of drop and vibration. Impact or vibration during transportation is transmitted to the product through the packing box. Dynamic force, acceleration, speed and displacement are not only the main reasons for the product being damaged, but also the main basis for cushion packaging design. Research packages in the impact, vibration external force
