| 摘 要： | 根据高速铁路系统组成,将高速铁路联调联试系统划分为6个子系统。基于工程控制理论,高速铁路联调联试系统结构采用多级层次结构和多级协调结构形式,建立用多变量动态方程组描述的数学模型。应用马尔可夫(Markov)过程分析高速铁路联调联试系统可靠性方法是:考虑子系统的独立性时,首先推导出首次系统平均失效时间计算公式,并采用可用度、失效频率和失效平均间隔时间参数评估子系统的稳态,然后用稳态概率描述系统的可靠性;考虑子系统间的关联性时,首先引入关联变量,将关联的子系统简化成串联或并联结构,然后对系统可靠性的边界条件进行评估。

| Abstract: | According to the system composition of high-speed railway,the testing and commissioning system for high-speed railway is divided into 6 subsystems.Based on engineering control theory,multi-level hierarchical structure and multi-level coordination structure are adopted for the testing and commissioning system structure of high-speed railway.The mathematical model described by multivariable dynamic equations has been constructed.Markov process is applied to analyze the reliability of the testing and commissio... |
