非包容转子失效危害性评估计算机辅助方法研究

为分析非包容转子失效对飞机造成的危害,在获得整机功能危险分析、故障树分析结果的基础上,提出一种计算机辅助的危害性定量评估方法。该方法基于蒙特卡洛模拟思想,通过模拟失效过程,能够计算不同非包容模式下的危险概率,进而为飞机设计完善与改进提供可信的依据。最后通过仿真分析表明方法的有效性。

Research on Harmfulness Assess Methods of Aircarft in the Case of Uncontained Turbine Engine Rotor Failure Aided by Computer

In order to identify the hazards to an aircraft in the event of multiple uncontained rotor debris bursting out,based on the results of aircraft level functional hazard analysis and using fault tree analysis,a method aided by computer of harmfulness assess quantitative of aircraft in the case of uncontained turbine engine rotor failure is proposed in this paper.Based on Monte carlo method,the method can calculate the probability of the hazard combinations resulted from multiple system failure by simulate the...
