“…There are many factors that effects passenger ride comfort, in which the vibration is the fundamental or primary factor [4]. Many people are faced the whole-body vibration (WBV) in their occupational life, specially the drivers and passengers of various vehicles, such as trucks, cars, trains and buses [5].…”

Abstract. In this study, the Whole-Body Vibration (WBV) was analyzed on the standing and seated passenger during off-peak operating hours when train was on the track. The experiments were conducted on two car train at one constant location (bogie-1, which is near to driver's cabin) during downward direction from KL sentral station towards Titiwangsa station. The aim of this study was to analyze that, in which posture of passenger's exposures the maximum level of WBV. Since, one passenger was performed the whole journey in standing posture whereas, the other passenger was in seated posture. The result obtained from experiments for the RMS accelerations (Arms), maximum acceleration (Amax) and minimum acceleration (Amin) during the trip. As per standard ISO 2631-1, the daily vibration exposure (A8), Vibration Dose value (VDV) and Crest Factor (CF) of this trip for both standing and sitting orientations were calculated. Results shows that the seated passenger was exposed to longer periods of continuous vibration as compared to the standing passenger. Whereas, the Vibration Dose value (VDV) value was greater than the action value as per ISO 2631-1 and within the limit values. The study concluded that whole body vibration transmitted towards both passengers either standing or seated during their journey. But in overall results comparison of both orientations, the seated passengers gained higher vibration than the standing one.

“…To examine the effect of this force on the vehicle dynamics, Equation (15) with different value of m f is inserted in right side of Equations (1) and (9). The simulation results about effects of damping force from linear generator results are shown in Figure 9 and provement is more remarkable in lateral and rolling direction than vertical direction.…”

“…The peak value with 1.2 m/s 2 /mm at 0.6 Hz is found. According to the [9] which studied about ride comfort of high speed train based on ISO-2631 (guide for evaluation of human exposure to whole-body vibration), the vibration of frequency range in 4 -12 Hz for the vertical direction and 0.6 -2 Hz for the lateral direction are sensitive to human body. Since the vibration of frequency for vertical direction is outside of the range 4 -12 Hz, it seems that the ride comfort for vertical direction couldn't be a major concern in this case.…”

This paper deals with a study on the dynamic behavior of 600 km/h wheel-type train propelled by superconducting linear synchronous motor (LSM). This train is of a traditional wheel-on-rail type with traction motors on wheel-bogies. However, for the 600 km/h speed, on the both sides of each vehicle, superconducting LSMs are attached and the ground coils are installed on the guideway. In this case, the guideway irregularities act as disturbance to the vehicle causing deterioration of ride comfort. And besides thrust force, the normal force could be created in superconducting LSM control, which influences vehicle dynamics during running. In this study, to examine the effect of guideway irregularity and normal force on dynamic behavior of proposed train, the vehicle dynamic model is driven and frequency analysis is performed through simulation. The simulation results show that the lateral directional acceleration is mainly influential to ride comfort; however this could be reduced effectively by electromagnetic damping force from linear generator. It is also shown that the normal force effect from superconducting LSM control is limited even though the attractive normal force acts favorably to ride comfort.

“…Therefore, passenger comfort has become a priority among train operators. Based on previous researches, one of the major factors that affect passenger comfort level in trains is the vibration and vibration behaviour of the vehicle (Kim et al, 2009;Munawir et al, 2017). Not only vibration reduces the quality of the ride experience of the passenger, but it also affects the passenger's health (Zhou et al, 2016).…”

Urban rail is a widely used public transportation; the vibration from frequent rides may impact passengers. The rail vehicle’s vibrations can cause human fatigue and result in severe musculoskeletal problems to the passenger. This paper aims to identify the effects of passenger orientation, operation time and body mass index on passengers’ whole-body vibration on an urban rail in Malaysia. Real-time monitoring of the whole-body vibration was conducted using 23 full factorial designs of the experiment, which was analysed statistically using Minitab Software. The overall result of this study is that the passengers in a seated position had greater exposure to whole-body vibration, which is 0.3686 ms-2 than standing passengers, 0.2965 ms-2. Also, passengers tend to be exposed to greater vibration during an off-peak time of 0.4063 ms-2, than a peak time of 0.3706 ms-2. Lastly, overweight passengers were exposed to greater vibration, of 0.4063 ms-2, than passengers within the ideal weight range of 0.4000 ms-2. This study has statistically proven that all the factors were significantly influenced the vibration exposure to the passenger. The most significant factor towards the vibration exposure is the “Body Mass Index (BMI)”, in which the p-value is less than 0.001. This study concludes that the whole-body vibration of a passenger is affected by the orientation of the passenger, operation time and body mass index of passengers on urban rail service.
