“…The suspension system isolates the vibrations from the unsprung mass to the sprung mass, ultimately achieving ride comfort and good road holding capability. The advancements in technology over these years have led to the development and adoption of semi-active and active suspension systems over the traditional passive suspension system [6]. The variable damping coefficient approach is applied to the semi-active suspension to improve ride comfort, whereas the active suspension system uses an actuator that provides an external damping force in response to the real-time road profile to mitigate the effect of undulating road conditions [7].…”

This paper presents an advanced vertical control system using active suspension to stabilize the vertical motion of an in-wheel motor-driven electric vehicle. The design of the control system and conceptualization were carried out by mathematical modeling with integration with the quarter car model. A novel active suspension is developed through the model-based design to control the vehicles to move smoothly and continuously. Even though experimental validation is an effective and more accurate method to evaluate the control system, it is important to reduce the dependency on physical testing. Thus, a reliable simulation framework would be beneficial in the vehicle development process. In this paper, the hydraulic system is designed and simulated by using the Simcenter Amesim. For the dynamic vibration absorber, we are seeking to design a skyhook control to control the damping force by an electric damper, whereas the spring stiffness can be switched by opening and closing the fluid passage to the gas chamber. In the spring stiffness control, the stiff suspension can reach a ratio of 1.3 compared to the soft suspension. The objective of this research work was realized with the proposed simulation framework to test the effectiveness of suspension control system to improve ride and handling in a four in-wheel motor-driven electric vehicle.INDEX TERMS Active suspension systems, simulation model, in-wheel motor technology, hydraulic control, vertical control, skyhook control.

“…With the introduction of inerter into the feld of vehicle vibration isolation, the inherent form of traditional suspension "spring-damping" is broken, and a new "inerter-spring-damper" suspension (called ISD suspension) appears. Te vehicle ISD suspension has been widely studied by scholars, and it is proven to have good vibration suppression performance [7,8].…”

In this paper, the vehicle ISD (inerter-spring-damper) suspension and power-driven-damper control strategy are combined to the suspension design, and the power-driven-damper semiactive ISD suspension is proposed. The dynamic models of the passive suspension S1 and two semiactive ISD suspensions S2 and S3 are established. Based on the port-controlled Hamiltonian theory, the power-driven-damper semiactive control strategy is designed by analyzing the power transfer of suspension S3. Then, the parameters of the two models are optimized by the particle swarm optimization algorithm, and the optimization results show that the suspension S3 has better performance. The influence of the semiactive damping coefficient, the spring stiffness, and the inertance on the vibration suppression performance is investigated based on the suspension S3. The effect of parameter perturbation on power-driven-damper semiactive vehicle ISD suspension illustrates that the designed semiactive vehicle ISD suspension has better ride comfort in a wider range frequency and good robust performance.

“…Optimizing these systems and their mechanism can bring us higher efficiency, less energy consumption, and comfort. [1][2][3][4][5] Automobiles are machines that benefit from these kinds of systems. Like the engine, gearbox, differential, and braking system, suspension systems are quite complicated dynamical systems, which we considered analyzing.…”

In this paper, we analyzed the vibration of an automobile suspension system. The influence of tire pressure and arc angle, vehicle velocity, and road impact frequency on the tire stiffness and damping coefficient was considered in this analysis. Moreover, an experimental formula for tire damping coefficient based on automobile velocity and impact frequency was proposed. In addition, the effects of the automobile’s mass, mass moment of inertia, unsprung mass, and center of gravity on the amplitude and period of vibration were investigated. The body was considered rigid, and the tires and other unsprung-loaded accessories were particles of a four-degree-of-freedom system. The equations of motions were solved by the analytical Laplace transform method and validated using Runge-Kutta numerical method. Based on outcomes for an initial displace of the front axle, increasing the tire pressure from 0.2 to 0.8 MPa leads to a 40% increase and 70% decrease in front and rear axles, and declining tire arc angle from 50° to 30° increases the maximum displacement of the front axle by 13% and halves the period. Different excitation frequency values (5, 10, 50, and 100 Hz) were applied to the system, which produced a 31%, 8%, and 9% rise in amplitudes. We understood that the tire damping coefficient decreases on a logarithmic scale for an automobile with a speed between 1 and 25 m/s. Furthermore, alternation in mass does not affect body rotation, and the alternation of mass moment of inertia does not influence body displacement significantly.
