چکیده
This study presents evaluation of effect of in-wheel electric motors mass on the performance of passive and active suspension systems using matlab. Linear Quadratic Regulator (LQR) is one of more common control methods which is used to complete the design of the active suspension system in this paper .Unsprung mass is one of the important parameters which effects on road holding and ride comfort behaviors in the vehicles, this effect obtained in this work by comparing the performance of the two systems using standard tire and tire with In-Wheel Electric Motor. Also, modeling and simulation of quarter car model completed to construct the Simulink models of the systems using MATLAB software. The study summarized bad effect of increasing the weight of tires by add In-Wheel Motors to the passive and active suspension systems on the road traction and the vehicles drivers comfort, at the same time the active suspension system with in-wheel motor needs high actuator force to work compared to the same system without in-wheel motor.

متن کاملModelling and Test Verification of Suspension Optimal Damping Ratio for Electric Vehicles Considering Occupant-cushion and In-wheel Motor Effects
The damping ratio of chassis suspension is a key parameter for damping matching of in-wheel motor vehicles (IWMVs). Because the motor is attached to the driving wheel, the initial design method of the damping ratio for traditional cars is not entirely suitable for IWMVs. This paper proposes an innovative initial design method of the damping ratio for IWMVs. Firstly, a traveling vibration model ...
