Abstract:Based on the response data of the frontal impact test of the trolley, the frontal impact simulation and analysis of the double-tube model of the trolley were carried out using finite element software. Starting from the thin-wall deformation mode, acceleration and energy curve changes as response indicators, the error between simulation and experiment is studied. With the goal of improving the simulation accuracy of the model, the influence of strain rate effect on the collision response is studied, and the def… Show more
