利用实验数据求取可靠度的计算机辅助图解法

The Computer-Aided Graphic Method For Solving The Effectiveness Based on Tested Data

可靠度是概率设计的一项定量可靠性指标，本文介绍了一种根据应力－强度模型，利用实验数据求取可靠度值的计算机辅助图解法。它通过高级语言与数据库的数据传递，编写与ＡｕｔｏＣＡＤ的接口程序，在ＡｕｔｏＣＡＤ工作环境下，借助于Ａｕｔｏｌｉｓｐ功能，实现了图形的自动生成及未知参数的求解。

The effectiveness is a quantitative reliability index in the probabilistic desingn. Based on the stress-strength model, this paper presents a computer-aided graphic method for finding the effectiveness value by using tested data,it compiles the interface programe of Auto CAD,by transmiting data in data base with high level computer language.Under the drawingsupported circumstances of AutoCAD,it realizes the graphs to be automatically drawed and the unknow parameters to be solved by means of the function of Autolisp.
