摘要:
铝合金 A 型车体是目前我国城市轨道交通车辆中应用最为广泛的典型车体，其底架承担着吊装部件、传递动力等作用，技术要求高，加工制造困难。为此，通过剖析底架加工技术要求，设计工艺方法、规划加工工序，展现底架加工从无到有的详细制造过程。其中，平面公差分配方法、测量补偿工艺、多工序钻孔循环等加工工艺能为同类产品的制造提供有效借鉴，是底架加工标准化作业施工的典范。
Abstracts:
The type-A aluminum alloy city railway car-body is the most typical vehicle structure widely used in city railway vehicle market. Its underframe bears the functions of hoisting components，transmission power and so on，featuring high technical requirements，difficult processing and manufacturing. Through an analysis of the technical requirements for the underframe processing，the design process method and the planning processing procedure，the detailed manufacturing process of the underframe processing is fully displayed. Its plane tolerance distribution method，the measurement compensation technology，the multi-process drilling cycle and so on can provide reference for the manufacture of same products，and serve as the standardized operation of the underframe processing.
