“…The air flow inflates the air to the pneumatic spring through two valves that are controlled using a control signal. Hence, the air pressure is always changing inside the air spring generating an active force to drive the seat in the vertical direction [69]. The seating suspension system structure shown in Figure 8 consists of a scissor structure mechanism, a hydraulic absorber and a pneumatic spring.…”

“…Therefore, the FXLMS was found to be able to attenuate the vibration at 20 Hz where the low frequency was considered in the range of 0-30 Hz. Additionally, the adaptive controller mechanism was proposed to compensate the seat suspension system in terms of the driver mass variation [69].…”

Drivers of heavy trucks are exposed to large amounts of vibration which can lead to serious health risks. Many suspension systems/methods can be used to isolate these transmitted vibrations, such as vehicle suspension systems, cabin suspension systems and seating suspension systems. The central idea of the work is to identify the research gaps and raise our future research questions in this specific area. The novelty of this paper is proposing a model predictive controller for active vibration control of seating suspension systems. A systematic literature review of the existing work of the vibration control of seating suspension systems has been conducted. Various control techniques that are used in the seating suspension systems have been summarized and evaluated. This paper focusses on the biodynamic model of the driver and seat for the first step needed in the design of the seating suspension system. Then, it illustrates the different types of the system vibration controls and their performance evaluation methods. At the end, the paper details several active seating suspension systems including their actuation system structures and control algorithms which are used in the heavy vehicle trucks.

“…The system can control the suspension well in the range of 0.5-4 Hz and can reduce response amplitudes under different mass load conditions. An active seat suspension incorporating a hydraulic shock absorber and an active pneumatic spring ( Figure 5) was developed in [52][53][54]. In this seating system, a hydraulic shock absorber is connected to a scissor-like frame for vibrational energy absorption, while a pneumatic spring is attached to the bottom of the seat and a rod of the frame to produce the corresponding compensation force.…”

As a major device for reducing vibration and protecting passengers, the low-frequency vibration control performance of commercial vehicle seating systems has become an attractive research topic in recent years. This article reviews the recent developments in active seat suspensions for vehicles. The features of active seat suspension actuators and the related control algorithms are described and discussed in detail. In addition, the vibration control and reduction performance of active seat suspension systems are also reviewed. The article also discusses the prospects of the application of machine learning, including artificial neural network (ANN) control algorithms, in the development of active seat suspension systems for vibration control.

“…e fundamental method of evaluating the effectiveness of vibration reduction system is to perform an experiment in the laboratory [8,9]. Unfortunately, the duration of the test and its high cost are the important aspects when the test must be performed repeatedly for different design parameters of the system.…”

e paper deals with the global sensitivity analysis for the purpose of shaping the vibroisolation properties of suspension systems under strictly defined operating conditions. e variance-based method is used to evaluate an influence of nonlinear force characteristics on the system dynamics. e proposed sensitivity indices provide the basis for determining the effect of key design parameters on the vibration isolation performance. e vibration transmissibility behaviour of an exemplary seat suspension system is discussed in order to illustrate the developed methodology.
