Digital R&D Platforms for Railway Freight Cars
摘要
Abstract
Aiming at four engineering problems in the traditional sequential R&D mode for railway freight cars—low cross-disciplinary collaboration efficiency,insufficient module reuse,poor knowledge accumulation and inheritance,and lack of unified standards for R&D data management—this paper presents a framework for building digital R&D platforms that is developed using a problem-method-validation approach.The framework is composed of R&D process restructuring,modular reuse,knowledge engineering,and unified data interfaces,and is implemented via a rapid design system,a simulation platform,and a digital test management platform.This platform approach was compared with the traditional mode using the DQJY 40-ft container flat car as a case study.Key results are as follows:the full-process cycle from conceptual design to drawing delivery was shortened to 50 days(a 34%reduction);design changes dropped from 2 to 1.18 per car(-41.0%);computation time was saved by 70%and data-retrieval efficiency rose by 60%;the number of drawings and design workload of shop drawings were reduced by 40%and 60%,respectively;the design time for variants was cut by 70%and the design cycle for new products was shortened by 40%;the training cycle for new engineers was halved;quality issues were reduced by more than 40%.This platform system offers an effective solution to pain points in digital R&D for railway freight cars,and provides a replicable engineering practice and technical support for transforming rail transit equipment towards higher payloads,greater intelligence,and improved environmental performance.关键词
