【Abstract】 A comparative study of the stiffness of the frames of two 250 models of motor- cycle is carried out using the finite element method for calculating the combined structure of the plate and tube.An ideal form of frame,the relationship between the stiffness and the tube section and reinforced plate is discussed.Finally some suggestions for frame design are put forward.更多还原
