【摘要】 从宏观的角度考虑了破孔过程中的随机因素,提出了破孔压差的概念,把各个传火孔的破孔压差看作是服从正态分布的独立随机变量,建立了该过程的随机模型,并用Monte Carlo方法进行了随机模拟。所得结论对点火系统的设计安全性具有一定的指导意义。更多还原

【Abstract】 The breaking of vent holes is essentially a random process, which is influenced by many random factors. In this paper, the random factors are studied in a macroscope view, and a new concept, pressure difference of hole breaking, is presented, which is regarded as an independent random variable satisfied normal distribution. A random model is proposed and solved by the Monte-Carlo method. Results show that the conclusion of this paper can be a reference for the design of a safe ignition system.更多还原
