Research On Automotive Reliability Based On Service-after-sale Failure Information

Along with the people of quality awareness and the deepening quality management theory and practice of development, product quality concepts from simple requirements in accordance with the standards of the" compliance" quality, extend to the requirements for users in need of" applicability" quality, namely from the products of their own functional special quality, extend product reliability, price, packaging, logistics delivery and after-sales service the quality concept of broad sense. Quality management activities focused on the reliability, market research and product research development direction of the transfer of. In many of the quality indicators, product reliability is undoubtedly the most users care quality metrics. Automotive product quality competition, to a large extent competition of automobile products was reliability. Can be seen that to improve the reliability of the automobile, not only improve the brand image, improve customer satisfaction and loyalty, enhance the market influence, expand product sales and market share, but also reduce car cost of poor quality, thereby reducing the overall cost and improve the economic efficiency of enterprises. So the reliability evaluation, to find out the influence of automobile reliability is the main factor, control and improve the automobile enterprises is very necessary and urgent task.This article introduces compared the domestic and international research status reliability. Research for foreign vehicle reliability auto and auto parts, systematic conducted qualitative and quantitative analysis of reliability theory, for many years, large numbers of vehicles and components test and the market failure tracking statistics enable it to have the rich data, improving the vehicle and component reliability has accumulated substantial experience, and established a perfect reliability database.Campaired with Abroad, both in theoretical research, reliability techniques used in the reliability level of products, at present our country still is put in bigger difference. Detail in domestic and international reliability theory, discusses the automobile reliability research ideas and reliability of automobile.Discuss Reliability evaluation analysis method. Reliability test and data analysis of proposed method. Based on a miniature car and a mini bus two models of fault statistics, analyzes the company car product quality weakness, the vehicle fault rule, a detailed analysis of the effects of my company car of the main factors of reliability.On reliability improvement countermeasure are studied. From product design, automobile parts and manufacturing phases of the improvement of the reliability and puts forward the corresponding countermeasures.
