As a vehicle moves on roads, a complex vibration system of the running vehicle is formed under the collective excitations of\nrandom crosswinds and road surface roughness, together with the artificial handing by the drivers. Several numerical models\nin deterministic way to assess the safety of running road vehicles under crosswinds were proposed. Actually, the natural wind\nis a random process in time domain due to turbulence, and the surface roughness of a road is also a random process but in\nspatial domain. The nature of a running vehicle therefore is an extension of dynamic reliability excited by random processes. This\nstudy tries to explore the dynamic reliability of a road vehicle subjected to turbulent crosswinds. Based on a nonlinear vibration\nsystem, the dynamic responses of a road vehicle are simulated to obtain the dynamic reliability.Monte Carlo Simulation with Latin\nHypercube Sampling is then applied on the possible random variables including the vehicle weight, road friction coefficient, and\ndriver parameter to look at their effects. Finally, a distribution model of the dynamic reliability and a corresponding index for the\nwind-induced vehicle accident considering these random processes and variables is proposed and employed to evaluate the safety\nof the running vehicle.
