摘要

改进设计公式是提高设计公式精度的重要方法。均值与变异系数是分析设计公式精度的基础。分析比较相同设计公式在不同应用范围时的精度,或者分析比较不同设计公式在相同或不同应用范围时的精度,是评价设计公式改进效果的重要内容。建立设计公式改进效果的评价指标与方法,是选择和确定设计公式的重要依据。采用强度-载荷干涉模型,建立了比较单层厚壁圆筒爆破强度设计公式改进效果的可靠性评价指标和方法。在相同或不同应用范围时,分析比较了单层厚壁圆筒爆破强度四个计算公式的改进效果,可供工程设计人员在选择和确定设计公式时参考。

Abstract

Improving design formula is an important way of increase design formula accuracy. The mean value and the coefficient of variation are the foundation of analysis formulas accuracy. Accuracy analysis and comparison of the same design formula applied in different ranges or different design formulas applied in the same or different ranges is an important part of evaluating design formula improvement effect. Establishing evaluation index and method of design formula improvement effect is an important basis in selecting and determining the design formula. Using strength-load interference model,reliability evaluation index and method were established that comparison single layer thick-walled cylinder burst strength design formulas improvement effect. In same or different ranges of application,the improvement effect of four burst strength design formulas for single layer thick-walled cylinder is analyzed and compared,the results can be reference for engineers in selecting and determining the design formula.
