A Company B-type Vehicle Air-conditioning System Performance Improvement Research Based On FMEA

With the popularity of the car,the car plays more and more important role in people's life,the quality of the cars is becoming more and more attention,in recent years,as the laws of the state,automobile recall system also gradually established in China,the quality is also mentioned more and more important by the car manufacturer,at the same time,the car production is now assembly line,standardized production,once problems are batch problem,if the quality management is not strict or control doesn't reach the designated requirement,it is easy to cause quality problems,causing immeasurable losses to the enterprise.Air-conditioning quality is a major aspect of the vehicle quality problems,especially the quality of the vehicle air conditioning system,because the air conditioning system is complex,a simple changes parts will affect the parameters of the whole system,at the same time,the effect of air conditioning system with state space vehicle,vehicle,engine performance,such as the vehicle arrangement,the current research focuses on a single air conditioning parts and parts of the system,and the matching of the vehicle air conditioning system and air conditioning systems in different study is not enough,the effect of the environment,especially a good set of air conditioning systems produce different effects on different models,The improvement method is limited,so the performance improvement of vehicle air conditioning system has high research value.To meet the needs of the market,an enterprise in the aspect of quality control and technical improvement of the air conditioning system made some related research work,by applying the FMEA analysis method and the corresponding test,case analysis and other research methods,the original problem,A relatively complex automotive air conditioning system step down to details,finally summarizes several relatively independent analysis,simulation,validation and application and so on,this topic is from the aspects of the vehicle system to research vehicle air conditioning performance improvement,use FMEA method to list the causes of air conditioning effect limited,Analyze potential failure patterns,find out the key factors,and analyzing problems,show the improved scheme,then through test verify the improvement effect,use this method to Analyze,improve and verify the vehicle air conditioning system cooling,heating,defrost and demist,Achieve the goal of improving A company B-type vehicle air conditioning system.
