摘要

在汽车研发过程中，可靠性、耐久性是两个重要技术指标，是通过设计确立、试验验证、生产保证，并在使用中显现出来的产品的一种固有质量属性。本研究主要以可靠性增长理论和Duane模型为基础，建立可靠性增长试验里程和试验周期的推算方法；运用实验设计理论，提出试验工况构建方法，以不同的运行时间、载荷、物流模式为要素，预测用户使用率与失效率，并进一步分析失效原因；同时，根据初期试验数据建立可靠性增长预测模型，用于试验过程跟踪和风险管控。

Abstract

Reliability and durability are two important technical indicators in automobile research and development. A research-and-design and testing organization can increase inherent quality attributes by adopting a systematic approach based on statistical tools and clearly defined processes. The process affects the design phase, validation through testing, and quality assurance in production. On the basis of reliability growth theory and the Duane model, this study established an estimation method for the definition of the target mileage and specific test cycles in reliability growth testing. A construction method for defining test conditions was proposed that adopts the theory of the design of experiments. The simulation was conducted under a variety of typical test conditions including differing operation times, loads, and logistics modes to predict customer use and detect failures. Failure cases were then analyzed in detail. At the same time, a reliability growth prediction model was established on the basis of the initial test data and used for test process tracking and risk control.
