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。
In order to analyze the damage to the aircraft caused by the failure of the non-inclusive rotor, a computer-aided method for the quantitative evaluation of the hazard is proposed based on the analysis of the function of the whole machine and the result of the fault tree analysis. Based on the Monte Carlo simulation method, this method can simulate the failure process and calculate the probability of danger in different non-inclusive modes, so as to provide credible basis for the design improvement and improvement of the aircraft. Finally, the simulation analysis shows that the method is effective.
