Abstract

Buffer is an important safety protection device in the event of vehicle accident and its working stability directly affects the life of the occupants. Due to the influence of strain gauge size and other factors, the conventional experimental measurement data is not accurate enough. Moreover, the buffer experiment is disruptive and costly. In order to obtain more accurate data and reduce the experimental cost, finite element modeling method was used to carry out numerical calculation of aluminum alloy tubular buffer, and the energy absorption capacity and the fluctuation of crushing force were studied. A large amount of data and nephogram were obtained, which provided support for the in-depth study of the working principle of the buffer. The results show that with the continuous pressure of the indenter, the different parts of the aluminum alloy tube will undergo elastoplastic deformation and absorb energy continuously from the outside. Data analysis results show that the average crushing force is 2.625 kN. Although the stress distribution of pipe wall is more uniform, the fluctuation of crushing force is still very obvious. This study provides data support for the design and optimization of buffer parameters in automobile enterprises.
