摘要:
为维持高铁稳定运行,提升资源运输安全,在离线监督性学习算法的基础上,提出了一种轮轨关系在线检测技术。通过高速摄像机获取待检测图像,并进行拼接处理;计算加速度、轮轨力和轮轨间关系,依据关键部分的振动值得到列车的加速度值,以此判断列车是否处于平稳运行状态;通过间接测量法计算列车的横向力平衡方程和侧滚力矩平衡方程,得到轮轨力具体值;通过 k 均值算法聚类处理以明确各个样本的类中心,找出样本数量最少的类,设为异常类,完成高铁轮轨关系的在线检测。仿真实验结果表明,在稳定性、数据可靠性和实际应用方面,各项参数曲线变化幅度极为相同,曲线走向几乎一致,且使用后的轮轨接触状态较好,满足高铁轮轨关系在线检测技术的实际应用需求。
Abstract:
In order to maintain the stable operation of high-speed railway and improve the safety of resource transportation , an on-line detection technology of wheel rail relationship is proposed based on off-line supervised learning algorithm.The image to be detected is obtained through the high-speed camera and splicing processing is performed ; the acceleration , wheel rail force and the relation between wheel and rail are calculated to obtain the acceleration value of the train according to the vibration value of the key part , so as to judge whether the train is in a stable running state ; the lateral force balance equation and rolling moment balance equation of the train are calculated by indirect measurement method , and the specific value of wheel rail force is obtained ; through k-means algorithm clustering processing and clarifying the class center of each sample , the class with the least number of samples is found and is set as abnormal class to complete the on-line detection of wheel rail relationship of high-speed railway.The simulation results show that in terms of stability , data reliability and practical application , the variation range of each parameter curve is same , the curve trend is almost the same , and the wheel rail contact state after use is good , which meets the practical application requirements of high-speed rail wheel rail relationship on-line detection technology.
