摘要
本文根据数理统计原理和系统信息熵原理,针对复杂机械系统,提出一种适用于其可靠性评定的信息熵法。该方法是将部件的试验数据折合成系统的试验数据,作为系统试验的验前信息,而由二项式分布求任意置信度下的系统可靠度下限。计算方法简单实用,是复杂机械系统可靠性评定的较优方法。
In thiS paper, an information entropy nrethed for the sophisticated mecganical system reliability assessment is presented based on the mathematical statistics theory and the information entropy theory.The basic ideas of the methed are that the test data of the ports are converted into the test data uf the sys-tem,and are regarded as the foretest intormation of the system test,then the low limit of the system relia-bility can be computed by the binomial distribution on condition that the arbitrary confidence ievel.The method of calculation is very simple and practical,and is the optimum methed of the sophisticated me-chanical system reliabilitY assessment.
