Abstract: | The product and vehicle, through a packaging, constitute a complex product‐transport system in logistics. It is very important to obtain the frequency response functions of the product‐transport system and its substructures for the design of product packaging. In this paper, the product‐transport system is treated as a two‐substructures multi‐coordinate coupled system. It is composed of a product substructure and a vehicle substructure, which are connected by a packaging structure consisting of many packaging units. The multi‐coordinate coupled inverse substructure method is developed and used to analyse the dynamic characteristics of the product‐transport system. To verify the validity of this method for the product‐transport system, the experiment of a physical prototype is conducted. The results show that the predicted substructure‐level frequency response functions are in accordance with the measured. Copyright © 2013 John Wiley & Sons, Ltd. |
