摘要
针对转辙机缺口极易受到外界温度影响的特性,分析最小二乘曲线拟合多项式的原理及拟合方法,采用MatLab软件对缺口偏移量数据进行仿真实验,并比较其精度,使用多项式拟合对转辙机缺口偏移量进行预测。实验仿真结果表明,该方法可以有效地预测转辙机缺口的变化。
According to the characteristic that point switch loophole is easily to be influenced by external temperature,the paper analyzes LS curve fitting polynomial principle and fitting method,does simulation experiment on loophole offset data by MatLab software,compares the precision,and predicts point switch loophole offset by polynomial fitting.Experiment simulation results show that the method can effectively predict the change of point switch loophole.
