The purpose of this research was to analyze the possibilities for the application of vibration signals in real-time train and track control. Proper experiments must be performed for the validation of the methods. Research on vibration in the context of transport must entail many of the different nonlinear dynamic forces that may occur while driving. Therefore, the paper addresses two research cases. The developed application contains the identification of movement and dynamics and the evaluation of the technical state of the rail track. The statistics and resultant vector methods are presented. The paper presents other useful metrics to describe the dynamical properties of the driving train. The angle of the resultant horizontal and vertical accelerations is defined for the evaluation of the current position of cabin. It is calculated as an inverse tangent function of current longitudinal and transverse, longitudinal and vertical, transverse, and vertical accelerations. Additionally, the resultant vectors of accelerations are calculated.
本研究的目的是分析振动信号在实时列车和轨道控制中的应用可能性。必须进行适当的实验来验证这些方法。在运输背景下进行的振动研究必须涉及许多可能在驾驶过程中出现的不同非线性动态力。因此，本文涉及两个研究案例。所开发的应用程序包含运动和动力学的识别以及轨道技术状态的评估。介绍了统计和结果向量方法。本文还提出了其他有用的指标来描述驱动列车的动力学特性。结果水平和垂直加速度的角度定义为评估车厢当前位置。它是当前纵向和横向、纵向和垂直、横向和垂直加速度的反正切函数计算得出的。此外，还计算了加速度的结果向量。
