“…Research on seat vibration reduction is mostly carried out on the vertical displacement and acceleration of the seat [ 21 , 22 , 23 ]. This paper mainly focuses on the displacement and acceleration of the active seat suspension and discusses the two cases of no interference and interference, as shown in Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 .…”

“…Xia et al [ 22 ] proposed a hybrid controller using an advanced electromagnetic damper (EMD) system to meet the requirements of vibration isolation and energy saving for seat suspensions. Cvok et al [ 23 ] introduced the design of a rig that used a linear electric servomotor to exert accurately controlled vertical vibrations on the driver’s seat, which could provide a basis for extending ride comfort evaluation research in different directions.…”

Vehicle seats have a significant impact on the comfort of passengers. The development of seats is a field in which scholars are widely concerned. In this study, we add an electromagnetic levitation structure and design a new active seat suspension based on the passive seat suspension. Then, simulation research is carried out based on a C-level road surface combined with integral sliding mode control and state feedback control. The results show that both state feedback control and integral sliding mode control positively affect vehicle seat vibration reduction, and integral sliding mode control has a better anti-interference effect than state feedback control. At the same time, it is proved that the seat suspension has good working characteristics and economy.

“…The paper proposes a four-DoF chair as the gravity motion needed for flight. To the best of our knowledge, the ideas we mentioned have not been presented in the previously published papers [1]- [18]. As a result, this paper presents some new ideas in the implementation of motion chair control systems, including an adjustable speed control system and short distance stroke control system.…”

“…The seat height structure consists of a whole-chair adjustable vertical structure. Because each component has a single level of motion DoF, the researchers refer to the method used in [16]- [18] and identified inverse kinematic model based on the geometrical relationship between the connecting rods. By contrast, inverse kinematics involves obtaining the displacement or angles of each joint based on reverse engineering of the movement position and attitude of the simulator in space.…”

In this study, the proposed design of a motion chair with four degrees of freedom (DoF) provides the pilot with the tactile sensations required by the human body to increase the immersion of flight simulation training. The chair includes a seat pan, a back pad, and a seat height. For the development of the proposed mechanism structure, the modular design is used to achieve the required displacement and acceleration. In addition, inverse kinematics is also constructed to meet the actuation needs. The control system can achieve real-time closed-loop control using an industrial computer, a motion control card, servo motors and drivers. This enables the structure to reach destinations with the shortest motion time and completes the required T-curve motion trajectory. The displacement, velocity, and acceleration of the designed structure are analyzed using SimWise4D software to verify the performance specifications of the structure. The experimental results indicate that the four-DoF control meets requirements of displacement, velocity, and acceleration.

“…The subject of vibration comfort of adult motor vehicle users, as opposed to the issue of the vibration comfort of children transported in child seats, has been quite thoroughly explored. The comfort felt by a child differs to a large extent from that of an adult [37][38][39][40][41]. In addition, an adult can correctly determine the degree of perceived comfort, while in the case of a small child it is impossible.…”

This paper deals with the issues of the impact of vertical vibrations on a child seated in a child seat during a journey. Its purpose was to assess the impact of fastening the child seats and road conditions on the level of vibrations recorded on child seats. The paper describes the tested child seats, the methodology of the tests and the test apparatus included in the measuring track. The tests were carried out in real road conditions where the child seats were located on the rear seat of a passenger vehicle. One was attached with standard seat belts, and the other with the ISOFIX base. When driving on roads with three types of surface, the following vertical accelerations were measured: seat of the child seats, the rear seat of the vehicle and the ISOfix base. The recorded accelerations were first analyzed in the time domain and then in the frequency domain. Three indexes (r.m.s, rmq and VDV) were used to assess the vibration comfort. Research has shown that the classic method of fastening a child seat with standard seat belts is more advantageous in terms of vibration comfort. Calculated indicators confirmed the negative impact of separating the child seat from the rear seat of the vehicle using the IQ ISOFIX base.
