| 中文摘要: |
| 针对汽车悬架系统中常见的焊接结构，采用CAE技术对其焊缝的耐久性进行分析。为了考察焊缝模型各参数对焊缝疲劳寿命的影响，在前处理软件中建立不同焊缝单元倾角及厚度模型，并在nCode软件中计算焊缝部位的疲劳损伤。通过对比分析，建立各参数与疲劳损伤的相关性，为模拟焊缝结构的有效性提供参考。 |
| 英文摘要: |
| For the common welding structure in the automobile suspension system, CAE technology was used to analyze the durability of the welding bead. In order to inspect the relationship between the various model parameters of the welding bead and the weld fatigue life, the welding models with different angle and thickness were established in the former processing software, and the nCode software was used to calculate the fatigue damage. Through comparison and analysis, the correlation of the parameters with respect to the fatigue life was established, which could provide reference for the simulation validity of the welding structure. |
