In this study, the deformation, equivalent stress and strain energy were analyzed on the electric kick board emerging as a new means of transportation at the accident of a front collision according to each shape were analyzed. The largest part deformation happened at the handle, and the board part where the person’s feet was placed was seen to become weak. The equivalent stress was most visible at the board section, unlike the deformation results. In particular, the deformation and stress of model A which has a long and thin neck, have occurred greatly. Therefore, the longer the neck, the greater the deformation and stress occur. Among all models, the deformation and stress were the smallest at model C. As model A has a particularly thinner neck and board connection part, a large strain energy appeared. Therefore, it is considered that the connection needs to be reinforced thickly and firmly. On the study result, the thicker the board part of the electric kick board and the lower the body of the vehicle, the safer it is. The results of this study can be effectively applied to investigate the values of stresses and deformations, and strain energies through structural analysis without the fracture test at the front collision according to the shape of electric kick board.
