摘　　要：在不考虑温度影响的情况下,运用Matlab软件,对自制的无石棉纸金属缠绕垫片的压缩回弹试验数据进行曲线拟合,并预测了不同预紧载荷下的回弹曲线。结果表明:压缩回弹曲线拟合方程精度较高;预测的不同预紧载荷下的回弹曲线与试验曲线较吻合且精度较高。The compressive and recovery curves of non asbestos metal spiral gaskets were fitled by tile experiment data using Matlab software without considering the influence of temperature. And the recovery curves under differenl pre loading conditions were predicted. The results show that the fitted equations were precise. Tbese predicled compressive and recovery curves under different prcqoading coincided with experimental curves very well and were of high precision.
