Whole-body vibration (WBV) is a significant concern for vehicle users as it can negatively impact their health and comfort. As such, effective vibration isolation is critical in vehicle suspension design. The ability of a vehicle suspension to isolate vibrations depends primarily on the suspension design and the type of springs used. One type of spring that has proven advantageous for vibration isolation is the air spring. Air springs can vary frequencies and adjust their stiffness in response to different loading conditions, making them ideal for meeting both suspension load-carrying and occupants’ comfort requirements. Pneumatic (air) suspension has been in use in the automotive industry for several decades and has undergone significant advancements during this period. This paper presents a systematic review of pneumatic suspension since its inception. The review highlights different air spring modeling techniques, types of pneumatic suspension, and control methods. The study also discusses the functional flexibility of pneumatic suspension, its ability to offer a wide range of control options to drivers, and its broad application in almost all ranges of vehicles, including chassis, cabin, and seat suspension systems. In addition, this paper presents a summary of the pros and cons of pneumatic suspension and suggests future research directions. The advantages of pneumatic suspension include effective vibration isolation, improved ride comfort, and the ability to adjust suspension stiffness and ride height. On the other hand, the disadvantages include higher cost and complexity compared to other types of suspension. Overall, the findings of this review demonstrate that pneumatic suspension is a viable solution for vehicle suspension design, particularly in situations where vibration isolation and ride comfort are critical.

“…Для снижения уровня вибрации дорожных и строительных машин в целом и человека-оператора в частности, широко применяются системы виброзащиты, которые называютcz также системами подрессоривания [18,19]. Среди базовых подходов к решению данного вопроса можно выделить применение в качестве опор машины, кабины и кресла человека-оператора пневматических упругих элементов [6,11,12,17] и традиционных металлических пружин в сочетании с жесткими стержнями и шарнирами [2,5,8,9]. Также разрабатываются конструкции с использованием гидропневматических элементов виброзащиты кресла и кабины [16].…”

Air suspension of seat is one of the most important components of the system of vibration protection of the human operator of the vehicle. All vibrational energy transmitted through the suspension of the seat from the cab floor to the driver is stored, absorbed and later dissipated by means of elastic damping elements, turning into heat. An assessment of the intensity of thermal radiation from the air spring and the shock absorber during operation may further improve the design of existing seat suspension systems. As an example, we can mention the possibility of vibrational energy recovery, which in regular passive suspensions turns into heat when extinguished. The article presents the results of tests of the air suspension of the seat of the company Sibeco on a single-support test bench with a hydraulic drive manufactured by the Indian company BiSS. The purpose of the test is to study the thermograms of the surfaces of the elasticdamping elements during operation. An experimental setup, which includes the metal elements of the connection of the actuator of the hydropulsator test bench with a shock absorber and the suspension of the seat as a whole, as well as a force sensor built into the design of the stand, is described. The working diagrams of the shock absorber and air suspension of the seat at each fixed point in time of one minute are obtained. To measure the values of temperature and read surface thermograms the Testo thermal imager was used. The study was conducted on the harmonic mode of exposure. During processing and analyzing the obtained data, the nature of the heating of the outer surface of the shock absorber and the air spring, as well as the fact of reaching stabilization temperatures, were revealed. In conclusion, the reasons for the discrepancy between the intensity of thermal radiation of the air spring and the shock absorber of the seat suspension are given.
