Analysis of Steering Dynamics of Rhombic New Concept Car

A rhombic new concept car is characterized with a rhombic configuration of 4 wheels,which has the advantage of avoiding forward collision,excellent mobility,and low wind resistive factor over traditional cars.A linear 2 DOF vehicle model with three wheels was firstly used to analyze the steering dynamics of the rhombic new concept car,and the steering stability factor and yaw rate gain transform function were deduced.Furthermore,for more accurate simulation,a nonlinear 8 DOF vehicle model was used to analyze the step steering response of the rhombic car.Simulation results prove the feasibility of rhombic configuration of wheels because its steering dynamics is comparable to that of vehicles with traditional configuration of wheels.
