摘要
目的获取产品运输包装系统各部件的动态特性。方法采用多级系统分布解耦法,结合二级刚性耦合系统逆子结构理论,推导由产品、车辆部件水平和系统水平频响传函预测关键部件频响传函的理论公式。搭建电机-洗衣机-车辆三级刚柔耦合运输系统,对理论方法进行验证。结果通过在线实验验证,基于理论预测得到的关键部件频响传函和测试值相吻合。结论研究结果为产品运输包装设计和优化提供了参考依据。
This study aimed to acquire the dynamic characteristics of the components of the product transportation packaging system. With help of distributed decoupling method and inverse sub-structuring theory of two-level rigid coupling system, the theoretical formula was deduced for predicting the frequency response function of key components according to the frequency response function of products, the vehicle component level and the system level. The motor-washing machine-vehicle system was set up to verify the correctness of the theory. Based on online test and verification, the predicted frequency response function of key components based on the theory was consistent with the test value. The study results can provide reference for designing and optimizing transport packaging.
