Abstract：

In order to shorten the manufacturing period,decrease the manufacturing cost and improve the manufacturing process of high-speed vehicle,stretching experiments of high strength aluminum alloy plates of ten types used in high-speed vehicle were done with the multi-test machine controlled by computer.Based on the mechanical property parameters and stress and strain relationship gotten by the stretching experiment,finite element simulations of punching aluminum alloy plates of ten types were made with finite element method according to "Performance Testing and Forming Method og Sheet Metal"regulated by the national standard of China.The limit bending radius and the limit bending angles of ten materials were gotten under thirty cases and the analysis results were used to guide the punching test of high strength aluminum alloy and to optimize the test cases.Therefore,the numbers of punching test cases are reduced.The cases of the test can be minimized to get the basic bending property parameters
