简介:摘要:伴随着电力机车的发展,交流AC27.5 kV供电应用越来越广泛。本文对交流27.5KV牵引供电系统的故障案例、接线方式及特点、三相不平衡补偿、电力机车牵引与制动原理做了简单介绍,争取为牵引供电系统的不断优化与同样问题的处理提供帮助。
简介:随着现代制造业的迅速发展,以净成形(NetShape)或近净成形(NearNetShape)为代表的塑性成形技术正日益受到重视。其中等温精密成形技术由于极大地改善了材料的塑性,提高了材料的充填能力,能够成形形状复杂、尺寸精度高的锻件,因而在近些年受到了普遍的重视。对于在航空发动机中有重要应用的发动机转子,其圆周上通常有大量叶片,叶片不仅薄而且呈扭曲状,制造难度很大。此外,为了满足构件减重的需要,许多结构锻件通常被设计成薄腹板并带有纵、横内筋的结构,这种薄腹高筋结构给构件的加工带来很大困难。对于大型薄腹高筋复杂构件,若对其使用性能要求不高,国外多采用精密铸造的方法成形,我国精密铸造技术与国外先进国家相比尚有一定差距,此类铸件的内部缺陷较多,加工成本较高,成品率较低。
