A review of the current use of multibody dynamics methods in the analysis of the dynamics of vehicles is given. Railway vehicle dynamics as well as road vehicle dynamics are considered, where for the latter the dynamics of cars and trucks and the dynamics of single-track vehicles, in particular motorcycles and bicycles, are reviewed. Commonalities and differences are shown, and open questions and challenges are given as directions for further research in this field.

“…IQUID sloshing is of interest in fundamental fluid dynamics and control research, as well as for various practical applications including liquid-filled natural gas carriers, elevated water towers, underground motion when subject to earthquakes, fuel tanks for the automotive industry, and preventing dam breaking [1][2][3][4][5][6][7][8]. This is especially important for the aerospace industry in order to accomplish long and complicated space missions, such as orbit insertion, orbit maintenance, and momentum unload, as modern spacecraft require large amounts of liquid propellant, most of which have high transparency and fluidity.…”

Accurate Measurement of Nonlinear Liquid Sloshing

The accurate measurement of nonlinear liquid sloshing in a liquid-filled spacecraft is of importance for precise flight control. In this paper, a novel noncontact method combining the fringe transmission technique with the liquidlevel reflection technique has been developed to accurately evaluate such behavior. To do this, a printed fringe pattern was first placed underneath a transparent test tank with fabricated calibration tails on the wall and, when viewed from above with a high-speed camera, a series of distorted transmission-fringe images with reflected images of the liquid level at different times during the sloshing process were achieved. Combing the quantitative relationship between the shape of the liquid surface and the distortion of the transmission fringes, as well as considering the height curves of the liquid level, the three-dimensional dynamic deformation field could be calculated using multidirectional Newton iterative algorithms. Both the dynamic deformation field of the liquid surface and the residual liquid volume in the tank could be accurately measured at the same time. An experimental verification was carried out, and the results obtained demonstrated the feasibility and reliability of this new method.Superscripts i, j = index of coordinates in x and y directions n = number of scattered points

“…The dynamic safety limits of a partly-filled tank truck are thus expected to be lower than those predicted from the quasi-static analyses. While a number of studies have investigated nonlinear dynamic fluid slosh using computation fluid dynamics (CFD) methods, the integration of a CFD model to the vehicle models has been attempted in only a few studies due to excessive computational demands of CFD analyses and extensive coordinates transformations [5,6]. Moreover, the validity of the CFD models has been demonstrated in a limited sense under nearly linear conditions.…”

The liquid cargo movement within a partly-filled tank truck affects its braking, roll dynamics and directional performance in an adverse manner. In this study, the braking performance of a partly-filled tank truck equipped with different baffles designs is investigated considering dynamic fluid-structure interactions. The validity of the computational fluid dynamic model is examined through laboratory tests conducted on a scale model tank with and without baffles. The measured responses to harmonic excitations revealed three-dimensional nature of the fluid motion and couplings between the lateral and longitudinal fluid slosh. Several spectral components were observed for the transient slosh forces, which could be associated with the excitation, resonance, and beat frequencies. A dynamic pitch plane model of a Tridem truck incorporating three-dimensional fluid slosh dynamics is subsequently developed to analyze the fluid-vehicle interactions under straight-line braking maneuvers. The results show that the vehicle responses are highly influenced by the slosh-induced force and moment.
