Abstract

A change in component design could help achieve objectives in lightweight construction. However, lightweight component design can incur serious distortion problems after the final heat treatment due to reduced stiffness or asymmetries in the mass distribution. The analysis of design modification through geometrical variations and their consequences on the distortion behavior through experiments can be costly and time consuming. In this paper, using 3D simulation models, different modified lightweight geometries are simulated. Using these simulation results, the authors try to understand the complex distortion behavior and correlate it with the effects of design modification.

摘要

部件设计的改变有助于实现轻量化结构的目标。然而，由于刚度降低或质量分布不对称，轻量化部件设计在最终热处理后可能会出现严重的变形问题。通过实验分析几何变化导致的设计修改及其对变形行为的影响可能成本高昂且耗时。在本文中，使用三维模拟模型对不同的改进轻量化几何形状进行了模拟。利用这些模拟结果，作者试图了解复杂的变形行为，并将其与设计修改的效果相关联。
