摘　　要：介绍了铝合金减震塔正向开发验证中使用的熔模铸造、砂型铸造和真空高压铸造三种不同铸造工艺,对比分析了三种铸造工艺及对应材料铸造出的零件在微观组织、力学性能以及连接性能上的差异。最后,根据实际生产使用过程中的应用情况,总结了三种铸造工艺的优缺点。Three kinds of casting processes, investment casting, sand casting, and high vacuum assisted high pressure casting, for the production of aluminum shock tower were employed at the development stage. Differences in the microstructure, mechanical properties, connection performance and Al alloy materials for the shock towers produced respectively by three kinds of casting processes are compared and analyzed. Finally, according to the practical production and application results, the advantages and disadvantages of three kinds of casting processes producing aluminum shock towers are summarized.
