“…Bae et al 11 developed a new methodology of identifying fundamental fatigue load from observed data by using engineering data analytics techniques. Following the results of a finite element method (FEM) analysis previously computed for load hypothesis, Gutie´rrez-Carvajal et al 12 presented a case study of the fatigue test performed over a bolster beam of a railway vehicle. By combining PAVE test and virtual fatigue analysis technique, Sun et al 13 analyzed the fatigue life of the integrated body structure of a light commercial vehicle, and the correlation between CAE analysis and PAVE intensified durability test is validated.…”

The working device of wheel loader undergoes complicated load cycles in operation with changing attitude all the time. However, it is difficult to duplicate the exact load history in lab. The common practice is to apply a fixed load attitude and equivalent load, to the working device to assess its fatigue life. In this paper, a modeling technique to calculate equivalent attitude and equivalent load is proposed. In the process of equivalent model establishing, the damages at critical points are considered. The finite element method is used to obtain the strain time history to compare with tested data.

The human vibration is a multidisciplinary subject involving many disciplines. A special area in the field of vibration research is the transport system. The paper presents the results of preliminary tests, the aim of which was to analyze the propagation of vibrations forced by the movement of the vehicle floor on persons sitting in a car. During research vibration were registered in measurement nodes, in which the composition always included the signal of oscillation of the enforcing plate and specific locations on the human body. This paper presents results of vibration recorded on the extinction plate and on the head of the passenger.

Wheel-rail contact phenomena is problem considered in many scientific manuscripts. Mostly the research is focused on wear, friction and forces analysis. This paper presents research on rail vibration generated due to rail vehicle passage. The problem investigated was the influence of wheel slip phenomena on vibration of rail. The locomotive wheel slip can be caused due to braking, flat wheel or defect (wear) of rail surface. Therefore, results of presented investigations can be useful for many applications, including rail vehicle driving monitoring system, control system, especially due to braking distance or diagnostics of wheels of railway tracks. The research was taken place on experimental test track. For the complex analysis horizontal and vertical vibration were measured. The investigation requires regular train vehicle drive condition, where the wheels are rolling on the rail surface without wheel slip and second case for drive process including wheel rolling and wheel slip (friction rolling and sliding). The vibration signals are non-stationary thus its processing should be conducted simultaneously in the time and frequency domain, as time-frequency representation (TFR). For this purpose, Short Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) can be employed.
