【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200.83,19.34mm,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。
[Abstract]:Aim to apply the finite element analysis technique to the analysis and optimization of the compression and vibration resistance of liquid crystal TV packaging. Methods the finite element models of LCD TV, cushioning pad and corrugated paper box were established by Ansys Workbench software. The paper simulates the deformation and the vibration of the package in the process of transportation and storage. Taking the mass, natural frequency and maximum deformation of the package as the objective function, the multi-objective optimization design of the liquid crystal TV cushioning liner was carried out. Results the maximum deformation of liquid crystal TV cushioning liner was 0.362 mm and the maximum stress of the package was 70 339 Pa.The modal analysis showed that the first order natural frequency of the package was 7.7471 Hz. After optimization analysis, the optimum design points for the height of cushioning pad and the depth of the top groove are 200.83mm and 19.34mm respectively. Compared with the original design value, the performance of the package has been greatly improved. Conclusion through the simulation analysis and optimization design of LCD TV, the structure size of cushioning liner can be improved, the damage rate of product can be reduced and the material can be saved.
