A high-fidelity approach for vehicle mobility simulation: Nonlinear finite element tires operating on granular material

Graph-analytical optimization of the transverse vertical cross-section of a contact zone between soil and an elastic wheeled mover

“…This relates to the stability of rheological coefficients during their deformation, and, therefore, completely eliminates the variability of elasticity and plasticity modules, coefficient of transverse deformation, the structural strength limits, etc. [8,9].…”

“…The geometric nonlinearity of the processes of soil deformation under the movers of mobile machinery predetermines the need for a graph-analytical study of the deformation dynamics not only of the deformed environment (soil) but the elastic [2,9,14] deformer (mover). In this case, the dynamics of a contour of contact surfaces of soil and the elastic mover sheath can be considered to be a certain generalization of the geometric characteristics of shape change in the soil microrelief under the mover of a mobile technological vehicle.…”

A Fuzzy Simulation Model for Military Vehicle Mobility Assessment

“…Lessem et al proposed NRMM adaptation to stochastic orientation [5], so that the model can be used for high resolution combat zones. In [15], a mobility simulation model based on tire flexibility and deformation of terrains is presented. This simulation model is limited to wheeled vehicles.…”

“…An extended Kalman filter based mobility estimation for unmanned ground vehicles is presented in [14]. The tire-soil interaction simulation based on absolute nodal coordinate formulation (ANCF) is developed by Recuero et al in [15]. A physics-based simulation model is discussed in [16].…”

Development of the Flexible Ring on an Elastic Continuous Foundation Tire Model for Planar Vibration of the Heavy Load Radial Tire

“…Simplified tire models with an analytical expression or purely empirically/semi-empirical formulae, such as the magic model [7], brush model [8], and LuGre model [9], etc., are used to investigate the longitudinal and lateral dynamics of the tire-road interactions with the computationally effective feature, while the structural elasticity and the flexible deformation of the tire belt and tire sidewall are ignored, leading to the existing deviation under certain manoeuvres. At the other extreme, taking the advantage the powerful computation and the composite characteristic [10], detailed tire models, such as the finite element tire model [6], absolute nodal coordinate formulation (ANCF) finite element tire model [11], and spectral element tire model [12], present the detail material feature and geometrical feature at the expense of much computation resource. Additionally, the detailed tire/road contacting feature can be investigated with the detailed tire and road model, while the large computation resource, the extensive finite element analysis (FEA)-oriented pre-processing, and the difficultly-obtained material parameters limit the extended application for vehicle dynamics.…”
