城市轨道车辆运行引发的环境振动问题近年来受到广泛关注。为了分析轨道地铁运行对沿线环境的振动影响,研究地铁沿线土体结构振动安全性,提出了一种基于FPGA和决策树算法的轨道车辆运行环境振动特征识别方案,开发了振动特征在线监测和自动识别系统。首先设计了轨道车辆运行环境振动信号监测装置,采集时域数据并计算了时域数据的傅里叶幅值谱;然后提取了均方根、峰峰值、均值、优势频率、幅值、波峰数和振动级等7个特征数据,参照ISO2631振动指标评价标准对数据标识后形成了训练数据集;运用C4.5决策树算法对训练数据集进行挖掘,构建了树形识别模型,并采用10折分层交叉验证方法评估了模型的性能;最后将识别模型植入软件,设计了系统的人机交互界面。评估结果表明,类别Green、Yellow和Red的识别正确率分别达到了93.4%、89.1%和87.3%,通过C4.5决策树数据挖掘算法能够有效识别运行环境的振动特征,加权正确率为90.5%。研制的轨道车辆运行环境振动特征识别系统为振动安全评估提供了技术支持。

针对传统的雷达K分布海杂波形状参数估计方法在异常样本存在情况下估计精度严重下降的问题,该文提出一种基于支持向量回归(SVR)和样本分位数比值的K分布海杂波形状参数估计方法。首先给定K分布杂波参数和分位数位置的值,根据K分布的累积分布函数计算样本分位数比值及其对数,然后建立以样本分位数比值对数为输入、待估计形状参数为输出的SVR模型,通过交叉验证确定SVR模型的超参数,最后训练SVR模型实现对K分布海杂波形状参数的稳健精确估计。仿真和实测雷达数据表明,所提方法的估计误差低于基于矩的估计方法的估计误差,并且与基于分位数的估计方法具有相近估计性能。此外,相比已有基于分位数的方法,所提方法的超参数容易确定,并且不依赖于查表。
