摘要

利用工况传递路径方法（OTPA, Operational Transfer Path Analysis）分析随机振动不同激励谱型、不同振动等级下产品包装系统的振动传递特性，结合非支配排序遗传算法（NSGA-Ⅱ, Non-dominated Sorting Genetic Algorithm-II）进行包装系统优化设计。实验结果表明，产品关键元件实测振动加速度响应曲线与OTPA方法合成的加速度响应曲线吻合良好，验证了OTPA方法的正确性；通过OTPA方法量化各传递路径的振动贡献量，对比识别出产品包装系统的主要振动传递路径；保持非主要传递路径的缓冲衬垫材料不变，应用NSGA-Ⅱ算法优化产品包装件系统中主要振动传递路径处的缓冲衬垫分配，有效降低了关键元件的加速度响应，减少在振动过程中的能量聚集，促使各传递路径的振动贡献量趋于均衡。实现了以缓冲性能为主导，同时兼顾环保性能与成本的包装系统优化设计，验证了优化方法的有效性，为产品包装系统设计提供参考。

Abstract

Using the Operating Condition Transfer Path Method (OTPA), Operational Transfer Path Analysis is used to analyze the vibration transmission characteristics of product packaging systems under different excitation spectra and vibration levels of random vibration, combined with Non Dominant Sorting Genetic Algorithm (NSGA-II), Non dominated Sorting Genetic Algorithm II for packaging system optimization design. The experimental results show that the measured vibration acceleration response curve of the key components of the product matches well with the acceleration response curve synthesized by the OTPA method, verifying the correctness of the OTPA method; Quantify the vibration contribution of each transmission path through the OTPA method, and compare and identify the main vibration transmission paths of the product packaging system; Keeping the cushioning material of the non main transmission path unchanged, the NSGA-II algorithm is applied to optimize the distribution of cushioning materials at the main vibration transmission path in the product packaging system, effectively reducing the acceleration response of key components, reducing energy accumulation during the vibration process, and promoting the vibration contribution of each transmission path to be balanced. We have achieved an optimized design of packaging systems that prioritizes buffering performance while balancing environmental performance and cost, verifying the effectiveness of the optimization method and providing reference for product packaging system design.
