Notes:
In the motor industry, the number of spot welded points is closely related to overall costof the vehicle assembly. A design based on experience is probable to lead redundant spot weldedjoints. Welded joints are critical in the structural performance, so it is hard to reduce the number.A measurable design index on the design of spot weld configuration is proposed in this study. Weoptimized the spot welding location and number in the lower control arm of the vehicle andautomobile body, as far as the structure retained the structural stiffness. In order to ensure therequirements, we use a sizing optimization of each spot weld stiffness for the global structuralrigidity. The survival index is defined the summation of resulted design variables, which is equal tothe number of survival in the series of sizing optimizations. With this design index, one canoptimally measure the importance of each spot weld joint and remove the redundant spot weldsfrom the structure design
