Lightweight Design and Experimental Study of Electric Draw-Bar Luggage

Abstract

In order to solve the inconvenience caused by the traditional draw-bar luggage when travel, an electric draw-bar luggage which can ride is designed. It is stable, reliable and easy to carry. The simulation model of the frame is established by ANSYS and the stress and total deformation of frame in bending condition, twisting condition, braking condition and turn condition are analyzed. The results show that the stress and total deformation of the frame are within the allowable range, and weight can be reduced through lightweight method.so lightweight design is carried out according to the analysis, then the optimization model of the frame is made and the correctness of the simulation model is verified by strain test. The final results show that the frame structure of the electric draw-bar luggage is stable and reliable, meets the requirements of use, and achieves good lightweight effect. The paper provides a way of idea and method for the design of electric draw-bar luggage.
