“…By using this model, selected driving maneuvers namely, zero-speed steering, lane change, ramp steer, J-turn, and braking at a deceleration of 0.6 g were carried out. Road profile of the National Fire Protection Association (NFPA) lane change maneuver [8] and superimposed graphical view of the simulation for the full laden vehicle at a constant velocity of v F =40 km/h are given in Fig.6.c and Fig.6 Reaction force variation at the joint G for the zero-speed steering case [6].…”

“…Hence, M B can be easily expressed as: Results of the MBD simulations indicated that compressive forces acting on the rods can be raised to a maximum value about 40 kN for the zero-speed steering maneuver which is the highest value obtained among the selected driving cases. Resultant reaction force variation at the spherical joint G (Fig.6.b) that corresponds to the maximum turning range of the wheel 5 (or pitman arm) for the stationary condition of the vehicle is seen in Fig.7.c as an example [6].…”

Vehicle steering mechanisms are generally considered as safety sub-systems due to their control and stability functions. Therefore, structural elements of a steering linkage should strictly resist the service loads without any overload failure. This paper reports an exemplary case study on the buckling evaluation of the multi-axle steering linkage tie rods which will be used in an 8x8 special purpose vehicle. In the first part of the study, full multibody dynamics (MBD) model of the vehicle including the steering linkage was composed by using Adams/Car™ commercial software. With this model, handling simulations were carried out to determine the service loads for various driving conditions. In order to verify the MBD model, reaction forces occur at the linkage joints were also calculated by using detailed finite element (FE) model of the entire system for the same driving conditions. In the final part of the work, buckling safety of the tie rods was assessed for the critical load case. In this way suitability of the system was evaluated in terms of buckling.
