The door system is the key systems for the safety of urban rail *** the urban rail vehicle system,the failure of the door system accounts for more than 30%of the total failure of the vehicle system,in order to overcome the subjectivity of the traditional reliability-based door maintenance（RCM） method,a new method of maintenance decision for RCM based on Proportional Hazard Model（PHM） is *** of all,provide preliminary maintenance decisions for the door by traditional RCM *** the proportional hazards model is introduced by considering the life cycle of key components,and the proportional hazards model of the door system is ***,the proportional risk model is applied to the decision-making of RCM door maintenance,and repair interval of the door system is *** case analysis indicates that maintenance cycle gotten by the proposed method is more reasonable than traditional RCM method.

Application of the Robust Approach and Finite Element Analysis in door system Static Design

引用

International Journal of Plant Engineering and Management 2010年第2期15卷 111-116页

The robust design approach based on Taguchi＇s design of experiment （DOE） coupled with the traditional finite element analysis （FEA） is applied to the static design of a sedan door. This method aims at shortening the design period, reducing the calculation cost and improving the competitive competence. First, the pe^ormance re- quirements, the control factors and the corresponding levels are determined to design a DOE table. Second, based on the schemes from the DOE table, sensitive control factors are distinguished from the results of the FEA method. Finally, the optimum design is chosen after comparisons and analyses of these performance response graphs. Performance results of the optimum design indicate that the application of the robust approach and FEA can greatly im- prove the quality of the door system, satisfy the requirements of products, underline the design purpose and shorten the design period.
