High-strength Steel Door-beam Design and Digital Simulation

摘要：

　　Due to the yield strength σs, tensile strength σb of high-strength steel is much higher than original one, it is applied in making autos structure parts to improve the security of passengers and reduce the weight of auto.To make the production of the cold-stamp parts easier, the paper analyzed the structure of a classical part, door-beam, and found that the surface of the part should be G1 continuity at least, rather than G0 continuity.The G1 continuity part has more uniform thickness, less inner strain, and more safety from cracking.
