摘　　要：主要介绍了一种耦合式催化转化器GBD封装设计流程,重点讲述了GBD范围的计算及校核方法,介绍了一种壳体缩径量核算方法,为减少传统封装过程中载体压损破坏及衬垫挤压断裂等过程失效,采用载体压装+缩径的组合工艺,通过设计选取的GBD范围,反推出封装过程中壳体原材料规格及最大压缩量。This paper introduces the design process of GBD package for coupled catalytic converter,emphasizes on the calculation and checking methods of GBD range,introduces a calculation method of shell shrinkage.In order to reduce the failure of carrier pressure breakage and liner extrusion fracture in the traditional packaging process,the combined process of carrier pressing and diameter reduction is adopted.And through the GBD range selected by the design,the shell raw material specifications and the maximum compression amount in the packaging process can be reversed in this paper.
