汽车结构中的铆接在建模中如何处理

liuxueshu

是否是用点焊来代替？如果是，请告知在ansys中如何设置，我只知道“点焊”这个词，不知怎么用。谢谢。

3 possibilities directly using keywords of LS-DYNA:
  
1.*constrained_spotweld
2. *contact_spotweld
3.*MAT_SPOTWELD_{option} since v. 960/ 970
  
from 1 to 3 more accurate and dedicate.

femman：
    能否给解释一下，我对这些命令不太懂，还请多多指教。

femman

you can find enough information in the theory manual and user manual.  
just try the example of using them. e.g "SPOT WELD Secures two plates"
most common is using first kind, even in FORD Cars.
after gather some experience and try more complicated usage. using contact(2) and material(3).
  
depends on what kind of task and accuracy.
