Research On FMEA And Its Implementation Methods In Chinese Automobile Manufacture

Reliability of automobile means: automobile product (whole automobile and components) in prescribe use condition, in prescribe phase, the ability of complete prescribe function. The reliability of automobile is basal and important reference for evaluate automobile's quality; also it is principal reference for customer select automobiles. For the manufacturing of automobile, better reliability not only can improve products credit standing, reduce waster, reduce compensation, avoid recall product, but also bring realism economic benefit.As a reliability analyse tool, before product deliver customer, the purpose of FMEA is help us evaluate latent bug and influence among produce design and produce technics, and take action in decision-making to eliminate them. due to FMEA easy operation and strong prevent function for quality bugs,now it has been applied to space navigation, nuclear industry, electron equipment, machine manufacturing etc fields in west advanced country.Use FMEA can prevent about 90% quality matters. present time, many oversea advanced automobile corporation, FMEA has became a core technic, but only few domestic corporation owned some design FMEA and process FMEA, of course, for these corporation, FMEA is very helpful for evade venture.Whereas hereinbefore reasons, the focal point in this dissertation are:1. Due to it is limitary apply FMEA in intricate system for analyse fault, so, writer conclude a viewpoint: utilize FMEA in intricate system for analyse fault that base on BAYESIAN NETWORK. Hope my effort can promote FMEA apply to our country automobile corporation, and improve FMEA's application universality and validity, and improve our country autombile production quality and market competitive.2. In view of the defects of the method of ascertaining risk priority number in FMEA, a calculation method of risk priority number based on probability reasoning is presented.3. Through reference internal and overseas literattre and investigation, to summarize the method in our country automobile corporation how to apply FMEA.
