PROBLEM TO BE SOLVED: To make clear an weld bond applicating position to improve rigidity etc. of the body, and to obtain maximum effect while suppressing influence to investment in plant and equipment and productivity, and cost up by minimum applicating position. SOLUTION: The system forms a finite element model about analysis object of the body etc., and performs the approximation processing of all joining regions by a spring joining. Real eigenvalue analysis of modal analysis or mode analysis is executed about three modes, that is the mode of one node twist, the mode of two nodes bending, and the mode of horizontal bending of the body, and distribution state of distortion of an approximated part by the spring joining is obtained. A part where distortion is large is decided as the part where weld bond is applied. COPYRIGHT: (C)2007,JPO&INPIT
