ANSYS软件在纸浆模塑包装制品力学分析中的应用

Application of ANSYS in Mechanical Analysis of Molded Pulp Packaging Products

结合纸浆模塑包装制品的特点,综述有限元ANSYS软件在纸浆模塑包装制品静态分析与动态分析两大方面中的应用。在静态方面,对有限元ANSYS软件在纸浆模塑包装制品(不同结构类型、不同成型参数以及不同成型工艺)力学分析方面的应用进行了阐述;在动态方面,详细介绍了瞬态动力学分析与随机振动分析在纸浆模塑包装制品力学方面的应用。最后对ANSYS软件在纸浆模塑包装制品分析中的不足做出改进,指出在保证纸浆模塑制品模型尺寸、形状、刚度等不发生明显变化的情况下,通过简化模型,降低计算工作量;在UG中实现实体模型的建立、有限元模型的生成和材料属性的设置等相关操作,并将生成的解算文件导入ANSYS中进行解算分析,以解决ANSYS中有限元模型生成困难的问题,以及需要对ANSYS软件建模功能进一步优化处理,使其运算结果更加精确、合理,为缩短产品开发周期与降低成本奠定理论与实践基础。

In this paper, in connection with the characteristics of the molded pulp packaging products, we introduced the application of the finite element ANSYS software in the static and dynamic analysis of the molded pulp packaging products. In terms of the static analysis, we introduced the application of the finite element ANSYS software in the mechanical analysis of the molded pulp packaging products while in terms of the dynamic analysis, we introduced in detail the application of the transient dynamic analysis and random vibration analysis in the mechanics of these products. At the end, we modified the shortcomings of the ANSYS software in the analysis of the molded pulp packaging products.
