In this study, an active suspension model is proposed to increase the driving safety and passenger comfort of the car, which is adversely affected by car-road interaction. In this context, the full car model with a driver is considered as eight degrees of freedom. All the motion equations of the car were determined by the Lagrangian method and converted into state-space forms. Then, these equations are solved precisely by using Euler's method in Matlab software. PID and LQR controllers are designed to reduce the vertical displacement of the passenger and the rotational movements of the car. In order to evaluate the performance of the designed controllers, two different road inputs and two different car speeds are taken into account. In the simulation results, the vertical displacement and acceleration values of the driver and the rotational movements of the car were examined. While the PID controller stands out in damping the displacement values at low speeds, the LQR controller is much more successful in other cases.

In this study, the full car model, which is exposed to a sinusoidal road input, has been examined to ensure the driving safety of the vehicles and the comfort of the passengers. In this context, the full car, including lateral and vertical movements, is modeled with fourteen degrees of freedom. The second-order equations of motion of the modeled vehicle were obtained using the Lagrangian method and reduced to first-order equations of motion using the state-space form. Then, these equations of motion were solved precisely in the time domain using the Euler method in the Matlab environment. To examine the lateral movements and the rotations of the vehicle in the pitch and roll axis, a sine wave with a wavelength of 5 m and an amplitude of 0.1 m was applied to the wheels of the vehicle. In the analysis, the right front wheel is exposed to a sinusoidal road input at t=0 s, while the left front wheel is exposed to a sinusoidal road input after the vehicle moves 2.5 m. Thus, both the pitch and roll motion of the vehicle will be examined in detail. In the study, four different vehicle masses 500 kg, 1000 kg, 2000 kg, and 3000 kg were taken into consideration and the effect of different vehicle masses on passenger and vehicle dynamic behaviors was investigated. In addition, the situation of passing vehicles at variable speeds from the given disruptive road input has also been examined. The maximum dynamic responses of the passenger and the vehicle were examined when the vehicle speed changed from 3 m/s to 50 m/s by 0.1 m/s. In the study, it has been observed that the vehicle mass and certain vehicle speed have effects on the vertical and lateral displacements and accelerations of the passenger and the vehicle

“…Within this framework, Eroğlu et al scrutinised the literature and effectively managed the automobile's vibrations by constructing a model that accounts for the interaction between the bridge and the car. This model was based on the Euler-Bernoulli beam theorem [10]. Hirzinger et al investigated the dynamic reactions of a mass-spring-damper system with 4 degrees of freedom using the Euler-Bernoulli beam [11].…”

The dynamic interaction between a flexible structure and a moving vehicle requires a complex and comprehensive analysis influenced by many parameters. because the tool and the flexible structure vibrate by affecting each other. In this study, considering the thermal conditions, the interaction between a flexible structure with simple bearing boundary conditions known as Euler-Bernoulli beam and a quarter vehicle with two degrees of freedom moving on it at a constant speed is modeled. The flexible structure used in the study is considered to have a constant cross-sectional area. However, the moving quarter consists of the vehicle mass, spring and damping elements. In the study, the temperature effect was applied to the flexible structure. The temperature of a structure has a great influence, especially on the modulus of elasticity of the structure. Therefore, the temperature effect significantly affects the rigidity of the flexible structure. This situation significantly affects the vibration characteristics of the flexible structure and the dynamic response of the vehicle moving on it. This section examines flexibility and dynamic vehicle dynamics in conditions above 60 degrees and below 60 degrees of normal temperature. As a result, the maximum displacement amount in the time-dependent vibration graph of the midpoint of the flexible structure increased as the temperature increased. However, the flexible structure has increased the maximum acceleration and displacement capacity of the moving vehicle model.
