Abstract

This paper presents a reliability modelling framework for automotive powertrains using a specially developed algebra, where all powertrain components and design and performance parameters are represented as formal computational objects of an idea class. Unlike previous known frameworks for reliability modelling, such as FMEA, FTA or FBS, the present study constructs the reliability model of a given powertrain topology from the topology only and does not require manual input of constitutive/performance equations, or the definition of a hierarchy of failure events. This tool is particularly useful in early stages of the design process, where the reliability of several alternative topologies may need to be evaluated a priori but a full-scale FMEA, FTA or FBS analysis would be impractical.

基于思想代数的汽车动力总成可靠性建模

本文提出了一个基于代数的汽车动力系统可靠性建模框架，其中所有动力系统部件、设计参数和性能参数都被表示为一个思想类的形式计算对象。与以前已知的可靠性建模框架(如FMEA、FTA或FBS)不同，本研究仅从拓扑结构构建给定动力总成拓扑结构的可靠性模型，不需要手动输入本构/性能方程，也不需要定义故障事件层次结构。这个工具在设计过程的早期阶段特别有用，在这个阶段，可能需要对几种备选拓扑的可靠性进行先验评估，但全面的FMEA、FTA或FBS分析是不切实际的。

期刊介绍： IJPT addresses novel scientific/technological results contributing to advancing powertrain technology, from components/subsystems to system integration/controls. Focus is primarily but not exclusively on ground vehicle applications. IJPT''s perspective is largely inspired by the fact that many innovations in powertrain advancement are only possible due to synergies between mechanical design, mechanisms, mechatronics, controls, networking system integration, etc. The science behind these is characterised by physical phenomena across the range of physics (multiphysics) and scale of motion (multiscale) governing the behaviour of components/subsystems.
