摘要
对安全阀弹簧压缩试验时载荷与变形试验数据进行线性拟合,求出它的刚度;对抗拉强度的试验结 果求出置信区间,减少了试验工作。
The paper analyzed the rigidity of the safe valve spring by means of the fitting method of the primary linear equation and confidence interval of the test results for tensile strength, which is good for analyzing the mechanical testing data.
