摘要

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.
