| 目的 针对嵌入式洗碗机的包装设计方案进行跌落仿真分析，进一步优化降低方案成本，得出符合生产制造的轻量化设计理论。方法 首先使用Hypermesh与LS-DYNA进行联合仿真，模拟包装件六面工况下跌落的响应情况；其次使用OptiStruct优化模块对下衬垫进行拓扑优化设计，根据衬垫变形情况设置合理优化工况，优化的约束条件加入衬垫制造约束，得到满足包装需求的最轻量化的方案。结果 优化后的最终方案可制造性加强，成本降低1.1元，且优化前后试验采集的易损件响应加速度有不同程度降低，达到优化目标。结论 轻量化设计理论在包装领域具有普适性，设计完成后，可以通过拓扑优化的技术路线进一步优化设计方案，降低包装成本，达到降本增效的目的。 |

| This paper aims to analyze the drop simulation of the embedded dishwasher packaging, to further reduce the solution cost, and finally obtain a lightweight design theory that is consistent with production. The joint simulation was conducted by Hyperworks/LS-Dyna. Firstly, the response of the package to the six-sided drop of working conditions was simulated. Secondly, OptiStruct optimization module was used to have topological optimization on the design of the bottom pad. Optimal working conditions were reasonably set according to the deformation of the pad. Manufacturing constraints were added to the pad to obtain the lightest weight solution that met the test requirements. The manufacturability of the optimized results was enhanced, the cost of the final solution was reduced by 1.1 yuan, and the acceleration response of the vulnerable part collected in the test before and after the optimization was reduced to varying degrees, which was in line with the optimization goal. Light weight design theory is universal in packaging. After the design is completed, the technical route of topology optimization can be used to realize cost decreasing and benefit increasing. |
