摘要

In the process of the actual product transportation, the enterprise usually to improve the vehicle turnover efficiency through the goods stacking form, reduce business costs. But because of the complexity of transport packaging system stacking itself, so that in the transportation process often falls, damage and even destroyed, resulting in unnecessary losses. In view of this, the paper based on the transport packaging dynamics as the starting point, first analyzes the typical factors influencing the dynamic characteristics of multilayer transport packages, and choose the stacking height and road roughness as the focus of the later analysis and the research object, focuses on the influence of random vibration on the safety of the goods and give the optimization scheme. Secondly, this paper introduces the virtual prototyping technology in the engineering field, through the simulation of ADAMS software to different stack height and road surface under the action of dynamic response characteristics, through the analysis of each layer of the transport package of each kind of vibration acceleration response curve under the experimental conditions, and obtains the influence law of pile dynamic code height and pavement roughness.
