有关研究数据表明,若汽车整车质量降低10%,燃油效率可提高6%-8%;若滚动阻力减少10%,燃油效率可提高3%;若车桥、变速器等机构的传动效率提高10%,燃油效率可提高7%。由此可见,伴随轻量化而来的突出优点就是油耗显著降低。本文基于ANSYS强大的求解器和前、后处理功能,并应用其参数化建模、结构分析和优化设计等模块功能对汽车发动机盖凹模的结构进行分析。通过分析揭示了冲压模具应力—应变和弹性变形的分布情况。本文根据静力分析结果对模具的一些筋板结构进行了尺寸优化以实现模具结构轻量化的目的,为模具的改进设计提供了理论依据。
According to the research data, the fuel efficiency can be increased by 6% -8% if the vehicle quality is reduced by 10%; the fuel efficiency can be increased by 3% if the rolling resistance is reduced by 10%; and if the transmission efficiency of an axle, a transmission and the like is increased by 10% %, Fuel efficiency can be increased by 7%. This shows that with the outstanding advantages of lightweight comes significantly reduced fuel consumption. Based on ANSYS’s powerful solver and pre- and post-processing functions, this paper analyzes the structure of automobile engine cover die with its module function of parametric modeling, structural analysis and optimization design. Through the analysis reveals the stamping die stress - strain and elastic deformation of the distribution. In this paper, based on the static analysis results, some rib structures of the mold are optimized in size to realize the lightweight structure of the mold, which provides a theoretical basis for the improved design of the mold.
