- Abstract
According to ISO 9000:2015 Quality management systems-Fundamentals and vocabulary, ISO/TS 22163:2017 Railway applications-Quality management systems, GJB 9001C—2017 Quality management systems requirements, product design work requires the output of characteristic analysis table. The important carbody characteristics of passenger train include dimension chain data in carbody design: carbody general assembly length tolerance, sub-assembly length tolerance, carbody general assembly width tolerance, sub-assembly width tolerance, carbody general assembly height tolerance, sub-assembly height tolerance, diagonal length difference limit of carbody transverse section, length difference limit of the diagonal lines of the roof, length difference limit of the diagonal lines of the underframe, carbody deflection range and sagging tolerance of the underframe end beyond the center of the sleeper beam. The connection methods of carbody sub-assemblies vary depending on the types of passenger trains. The dimension chain construction means of carbody assembly in aluminum, carbon steel and stainless steel are analyzed, and corresponding process control technologies are given. Through these dimension chain construction means and process control technologies, the important characteristic data of carbody is effectively controlled and meets the requirements of characteristic analysis table, ensuring the product quality.
