Abstract:
Spot-weld in most of vehicle modal analysis is modeled as a Rigid-beam, which is found that the stiffness of spot-weld can not be controlled and is highly dependent on mesh. A new simulation method of spot-weld is put forward by using Elastic-beam and modal analysis of a light bus is done. The experimental validation of real cars is completed and the results show that the simulation method of spot-weld using Elastic-beam is more accurate and effective.
