中文摘要:
      目的 将有限元分析技术应用于液晶电视包装件的抗压、抗振性能分析和优化设计中。方法 应用Ansys Workbench分析软件,建立液晶电视、缓冲衬垫和瓦楞纸箱的有限元模型。模拟包装件在物流运输和仓库堆码时,包装件受压时的变形受力情况,以及运输过程中的振动情况。以包装件的质量、固有频率及最大变形量为目标函数对液晶电视缓冲衬垫进行多目标优化设计。结果 经过静压分析,液晶电视缓冲衬垫最大变形量为0.362 mm,包装件所受最大应力为70 339 Pa;经过模态分析,包装件的一阶固有频率为7.7471 Hz。经过优化分析,缓冲衬垫高度和顶部凹槽深度的最佳设计点分别为200.83, 19.34 mm,与原始设计值相比,包装件各项性能得到了显著提升。结论 通过对液晶电视仿真分析和优化设计,可以对缓冲衬垫结构尺寸进行改进,降低了产品破损率同时节约材料。
英文摘要:
      The work aims to apply the finite element analysis technology to anti-compressive and anti-vibration properties analysis and optimization design of LCD TV package. With the application of ANSYS Workbench analysis software, the finite element model of LCD TV, cushion and corrugated boxes was built. The situation where packages were subject to deformation and stress as well as the vibration during the transportation was simulated in the process of logistics transportation and warehouse stacking. Multi-objective optimization design of the LCD TV cushioning pad was done with packaging mass, natural frequency and maximum deformation as objective functions. After the static pressure analysis, the maximum deformation of the LCD TV cushion was 0.362 mm, and the maximum stress of the package was 70 339 Pa. After the modal analysis, the first-order natural frequency of the package was 7.7471 Hz. After optimization analysis, the optimal design points of cushion height and top groove depth were 200.83 mm and 19.34 mm respectively. Compared with the original design value, all the performances of the package were improved significantly. Through the simulation analysis and optimization design of LCD TV, the size of the cushion structure can be improved, which saves materials while reducing the damage rate of the product.
