载人飞船温度控制系统故障可靠性数字仿真

Reliability Digital Simulation of Manned Spacecraft Temperature Control System Fault

根据载人飞船环控生保系统实验的各种故障信息，运用演绎法建立了以飞船密闭舱内大气温度超限为顶事件的故障树，并采用Ｍｏｎｔｅ—Ｃａｒｌｏ方法来获取系统工作的可靠性诸参量。最后通过仿真实验结果．对一些参数进行了讨论。

According to much experiment information of the manned spacecraft environment contril and life support system, the deductive method is used to build a fault tree for atmosphere of the spacecraft airtight cabin. Then some reliability parameters of system are acquired by the Monte--Carlo method. At last, some parameters are discussed on basis of simulation simulation experiment results.
