“…The TRC is computed based on the standards (see, e.g., BS 6841, 1987;EN 12299, 2009;ISO 2631ISO -1, 1997UIC 513R, 1994) and Sperling method (Van Eldik Thieme, 1961), presented as a function of carbody accelerations. Carbody accelerations are either measured from the field (Kim et al 2008, Zhai et al 2015 or computed from analyses of the results obtained from numerical models of train-track interaction (Choi et al 2013, Graa et al 2014, Kargarnovin et al 2005, Wu and Yang, 2003, Yau et al 1999. The field measurements require instrumentation of devices and complicated data recoding process which are considerably costly (Kim et al, 2008;Zhai et al, 2015).…”

Despite considerable importance of train ride comfort (TRC) in railway slab tracks, there is no TRC prediction model for the slab tracks in the available literature. In this regard, a practical TRC prediction model was developed in this research, taking into account all the track and rolling stock influencing parameters. For this purpose, a vehicle/slab-track interaction model was developed. The model was validated using the results obtained from a comprehensive field test. The effects of rail pad, resilient layer, subgrade, properties of rolling stock suspension systems and vehicle speed on the TRC were studied through a parametric study of the model in which random rail irregularities with various severities were considered. The results obtained were used to develop the TRC prediction model. The accuracy of the model predictions was evaluated by comparing them with those obtained from a railway field. It was shown that the TRC prediction model developed here is a reliable tool for estimation of the TRC from slab track properties, rolling stock parameters and track irregularities. Applicability of the model in the real world of practice is illustrated.

“…A mathematical model of a straddle-type monorail vehicle was developed in order to study its stability and the effect of tire modeling techniques on its dynamic response in the reference [16]. By studying the experimental results of Chongqing straddle monorail, an indirect detection method of the wheel out of round was put forward [17], [18]. However, the above references utilize the vehicle models of multi rigid body model, the influences of flexibility of vehicles on vibration do not taken into consideration.…”

The longitudinal drawbar and the lateral stabilizer bar of straddle-type monorail vehicle with the single-axle bogies have relatively long structure size. The multibar system leads to deformation during the driving process due to impact loads, even leads to influence on the dynamic characteristic of the hauling mechanism as well as the riding comfort of the whole vehicle. To evaluate the dynamic behavior of straddle-type monorail vehicle with single-axle bogies accurately, a full-scale rigid-flexible coupling multibody dynamics method is proposed based on multibody dynamics and finite element (FE) theory. The modal synthesis method is adopted to establish flexible multibody dynamics of the single-axle bogies. And then rigid-flexible coupling dynamic model of the straddle-type monorail vehicle is established with the ADAMS software. The validity of the full-scale model is verified. Finally, the influences of vehicle velocity, passenger mass, curve radius and the number of axles on dynamic characteristics are discussed. INDEX TERMS Straddle-type monorail vehicles, single-axle bogies, rigid-flexible coupling model, full-scale model, multibar system.

“…A vehicle-bridge-coupling system is used in the modeling step. The method of the simulation of rail vehicles and bridge interactions can also be used to set the dynamic model according to Lee et al [1][2][3] Lagrange equations were used in setting up this 15-degrees of freedom model. The model of the suspended monorail is analyzed according to Muller et al [4][5][6][7][8][9] Using the traditional modelling software SIMPACK, the dynamical characteristics of the monorail vehicles could be obtained in as in literature sources 6,7 which describe their dynamic performance.…”

This paper introduces two types of articulated monorails. The vehicle model of the traditional monorail is set up first, and a genetic algorithm is used to modify the parameters with the experimental data. Then, the two types of articulated monorail vehicle models are set up with the components and parameters of the model of the traditional monorail. By comparing the dynamic properties of the traditional monorail with the two types of articulated monorails, the advantage of the latter is realized. Finally, it has been concluded that the “non-bolster type” structure will be a better choice for vehicles passing a small radius curve. This analysis can be helpful in selecting the appropriate monorail system for particular conditions.
