摘要
尾减机匣是直升机尾减速器上的关键部件,铸件材质为ZL114A合金。根据尾减机匣的结构特点,对其进行铸造工艺设计并基于ProCAST数值模拟软件进行工艺优化。结果表明,在铸件的关键区域放置冒口、浇道并配合冷铁设计,能较好保证铸件厚大凸台补缩,生产出具有较好内部铸造质量的合格尾减机匣铸件。
The tail reducer casing is a key component of helicopter tail reducer.Its material is ZL114A alloy.In this work,according to the structural characteristics of the tail reducer casing,the casting process was designed and optimized based on the ProCAST numerical simulation results.The results show that,putting the risers,runners and chills at the key areas of the casing can better ensure the feeding effects of molten metal on the thick and large bosses of the casting,and the qualified tail reducer casings with better internal quality can be produced.
