Recently, electric vehicles have been developed in many places for various reasons. Although the stick model with beam clements is very convenient for the analysis and design, it may have significant errors due to the considerable simplifications. Especially, the difficulties exist at the modeling of joints, since the joints have complicated characteristics. In this research, a method for the joint modeling is suggested and verified. Beam elements are defined around a joint in the finite element analysis. The section properties of the joint elements are tuned to generate target responses by optimization. The target values are calculated by experiments or detailed analysis. The evaluated joints are be inserted in the full car model of an electrical vehicle.<br/>
