| 摘 要： | 针对振动测量数据超出测量系统原始设定范围造成的数据削波现象,介绍了回归分析和三次样条插值两种拟合方法.通过对测试数据进行建模预测的实例比较可知三次样条插值法的误差较小,应用此方法对飞机振动削波曲线进行恢复,可得到满意结果.

| Abstract: | Pointing to the phenomenon of clipped data due to vibrant data of a plane beyond the original scope,this paper introduces the regression analysis method and cubic splines interpolaton method.Through using the two methods to resume the clipped data,the cubic splines interpolaton's error is small.The cubic splines interpolaton method completes the resumption work of clipped curve successfully. |
