可靠度预测是可靠性设计中极为重要的一步。它是根据产品将要使用的元器件、功能、实际工作时所处的环境以及产品各个部分之间的相互关系,来推算所设计产品潜在的,而实际上又可以达到的各个部分和整机的可靠度。用计算机进行可靠度预测,可以提高计算的精度和速度。打印可靠度时间函数曲线,可以使可靠性的分析研究和数据处理更为直观、更为形象化,可以通过曲线了解必要的信息。本文给出用于可靠度预测的计算程序和打印串联、并联系统以及失效密度函数为正态分布时的可靠度时间函数曲线的程序。并以实例打出可靠度曲线。
Reliability prediction is an extremely important step in reliability design. It is based on the components to be used in the product, function, the actual work environment and the various parts of the product of the relationship between the projected product design, potential, but in fact can reach all parts of the machine Reliability. Computer reliability prediction can improve the accuracy and speed of calculation. Print reliability curve of time functions, you can make reliability analysis and data processing more intuitive, more visual, you can learn the necessary information through the curve. This paper presents a program for predicting the reliability and printing the series and parallel systems, as well as the time-dependent curve of the reliability when the failure density function is normal distribution. And hit the reliability curve with examples.
