| The Finite Element (FE) Method has gained immense popularity in the tire and automotive industry. To answer problems, the method is employed as specialized procedures as also via commercially available programs. Though identified as an effective analytical tool for simulating structural response, predicting coupled Vehicle-Suspension-Tire-Terrain transient responses, particularly accounting for the nonlinearities is still a challenge. Problems of this nature have been addressed by FE procedures that incorporate the Galilean transform but besides contact, all aspects adhere linear theory.; This research proposes to develop a novel technique for studying the nonlinear interaction of Vehicle-Suspension-Tire systems and time-dependent roadway asperities. The main thrust of this research will be to model the Tire-Terrain interactions by accurately taking in to account the nonlinearities induced by the time dependent contact conditions and the nonlinear stress and strain measures.; In order to consolidate this research as a useful application of the formulation and the resulting methodology, interaction between a Tire-Terrain module and a Vehicle-Suspension module will be developed in real time succinctly. Additional features will be incorporated such as quick simulation speeds, easy data extraction and post-processing ability, and particularly, flexibility and adaptability to interface with other models. |
