| Research Abstract |
In this study, we deal with spot weld position for building a spot welded structure whose vibration characteristics are insensitive to variation in spot weld positions. First, we reveal a spot weld finite element model suitable for vibration analysis and propose a guideline for plate mesh pattern surrounding a spot weld, affecting the model characteristics. Next, we examine the influence of spot weld positions on the vibration characteristics of a spot welded structure and present a guideline for spot weld positions to build the structure with a small variation in the vibration characteristics.
