摘要
随着新能源汽车市场的快速扩张,一体化压铸技术逐渐成为车身结构件制造的重要发展方向.本研究成功开发出了一种基于AlSi8系的高强韧免热处理压铸铝合金,通过精细化成分调控实现铸态下的高抗拉强度与伸长率.通过断裂拉伸试验和疲劳耐久试验开发了材料仿真卡片,并在某款新能源车一体化前舱铸件上成功应用,验证了其力学性能和铆接性能.
Abstract
With the rapid expansion of new energy vehicle market,integrated die-casting technology has gradually become an important development direction for the manufacturing of body structural components.A heat-free die-casting aluminum alloy with high strength and toughness was successfully developed based on AlSi8 series,achieving high tensile strength and high elongation in as-cast state through fine composition regulation.The simulation card was exploited through fracture tensile test and fatigue endurance test,and the mechanical properties and riveting properties were verified in an integrated die-casting front cabin of new energy vehicle.
