摘要
通过单边缺口三点弯曲试样的动态冲击试验，研究了几种车辆用铝合金对动态冲击的响应特性。从选材角度对比分析了几种铝合金的动态断裂韧性及裂纹扩展阻力。
By way of impact test of single edge notched bending specimen,a detailed study was performed on the dynamic response characteristics of some aluminum alloys that may be used in railway passenger car bodies.From the view point of material selection,we analyzed their dynamic fracture toughness and crack propagation resistance.
