Abstract
In a beginning design stage of an automobile body structure, it is demanded to design the body structure in consideration to a joint stiffness. However, the joint stiffness can not be obtained easily. If a tool to quickly and accurately obtain the joint stiffness is developed, it is useful in the body design. In this study, the method to estimate the joint stiffness values only by inputting the design parameters to the trained neural network is proposed. This method was applied to a spot welded joint structure.
