摘要
一体化压铸铝合金结构件因其具有高集成、轻量化、刚性好等优点,在乘用车车身上的应用逐渐增多,并且正在向大型化发展。压铸结构件大型化的发展对连接技术提出了更大的挑战。阐述了当前乘用车车身压铸铝合金典型应用部位,分析了大型压铸结构件应用面临的难点、困境以及大型化后连接技术方面的应对策略,展望了未来压铸铝结构件的发展趋势以及对连接技术的新要求。
Because of high integration,lightweight,good rigidity and the other advantages,the application of integrated high-pressure casting aluminum alloy structural parts in the passenger car body is gradually increasing,and the size of high-pressure casting aluminum alloy structural parts is also developing towards large scale.At the same time,the development of large-scale high-pressure casting aluminum alloy structural parts is bringing greater challenges to the connection technology.The Paper describes the typical application parts of high-pressure casting aluminum alloy for passenger car body,analyzes the difficulties and the connection technology corresponding strategies for applying large-sized high-pressure casting aluminum alloy structural parts.The development trend of high-pressure casting aluminum alloy structural parts and the new requirements for connection technology are also prospected.
