Optimization of suspension system of off-road vehicle for vehicle performance improvement

Research on the influence of virtual modeling and testing–based rubber track system on vibration performance of engineering vehicles

“…Since the ADAMS modeling is obviously insufficient, especially for a complex model with a curved shape, the virtual prototype of the rubber track system is established in Solidworks. This can be imported into the ADAMS by IGS format after simplification [17,18]. By being simplified, the mass of the virtual prototype is rather different from that of the physical one.…”

“…Meanwhile, the motion relationship of components is defined by various constraints. In the ADAMS/View, if there are no contact force between the various components of the rubber track system, there will be a direct influence caused by each other, so the contact force should be added [18][19][20].…”

Optimization of Vehicle Suspension System to Improve Comfort

“…M. Mahmoodi-Kaleibar et al used MSC ADAMS to carry out optimization of the suspension system implementing Genetic Algorithm which improved ride comfort as well as handling. Simulation results showed that the optimized system had lower camber angle variations [21].P.Senthil Kumar et al optimized a passenger vehicle suspension system considering stiffness and damping coefficient of shock absorber, stiffness and damping coefficient of the seat as input parameters. The design of experiments was planned by using L27 orthogonal array with 4 factors at 3 levels.…”

Relative kinematic and handling performance analyses of independent axle suspensions for a heavy-duty mining truck

“…Unlike the road vehicles, only a few studies, however, have investigated the relative performance characteristics of different linkage suspensions for off-road vehicles. The handling and ride comfort performances of an off-road vehicle with different suspension linkages such as double wishbone, Macpherson and pendulum were only briefly discussed by Mahmoodi et al (2013). Zhu et al (2010) evaluated the relative steady-state handling performance of a vehicle with planar and conventional suspensions in terms of yaw velocity, lateral acceleration and curvature response gains.…”
