“…Currently, the suspension mechanism is one of the most essential components of a car's system, largely determining the vehicle's safety and driving comfort. The suspension system transmits and regulates the static and dynamic forces and reactions between the vehicle and the ground (Ghazaly & Moaaz, 2014).…”

The design of the suspension system, which transmits force between the vehicle and the ground, is principally responsible for the driving comfort of a vehicle. Importantly, a vehicle's suspension system contributes to the reliability and precision of steering and control, as well as to the friction between the vehicle and the road. The suspension system is also responsible for absorbing and dampening road stress, so that we do not feel every bump on the road when driving. Linkages, springs, and shock absorbers are the three fundamental types of suspension components. This paper introduced the most common suspension problems and the symptoms that may indicate you need a suspension system repair, where it turns out that there is a set of problems common to all vehicle suspension systems, such as poor wheel alignment, faulty shocks or struts, damaged springs, failing ball joints, and faulty control arms. Now as a conclusion of this paper, the reader can know the most common suspension system problems in vehicles and thus how to deal with these problems.

“…An alternative to passive suspension is the use of an active suspension system that uses extra actuators together with passive suspension elements (e.g., springs and dampers) to effectively dismiss forces from the road excitation [ 17 ]. This type of suspension is used more often in commercial vehicles to increase the car’s stability and ride comfort on uneven terrains and ongoing research focuses on suspension control to reduce cost and power consumption [ 18 ]. Very few studies have proposed active suspension in EPWs; however, these were limited to simulations without a real-prototype [ 19 , 20 ].…”

Analysis of Whole-Body Vibration Using Electric Powered Wheelchairs on Surface Transitions

Wheelchair users are exposed to whole-body vibration (WBV) when driving on sidewalks and in urban environments; however, there is limited literature on WBV exposure to power wheelchair users when driving during daily activities. Further, surface transitions (i.e., curb-ramps) provide wheelchair accessibility from street intersections to sidewalks; but these require a threshold for water drainage. This threshold may induce high WBV (i.e., root-mean-square and vibration-daily-value accelerations) when accessibility guidelines are not met. This study analyzed the WBV effects on power wheelchairs with passive suspension when driving over surfaces with different thresholds. Additionally, this study introduced a novel power wheelchair with active suspension to reduce WBV levels on surface transitions. Three trials were performed with a commercial power wheelchair with passive suspension, a novel power wheelchair with active suspension, and the novel power wheelchair without active suspension driving on surfaces with five different thresholds. Results show no WBV difference among EPWs across all surfaces. However, the vibration-dose-value increased with higher surface thresholds when using the passive suspension while the active suspension remained constant. Overall, the power wheelchair with active suspension offered similar WBV effects as the passive suspension. While significant vibration-dose-value differences were observed between surface thresholds, all EPWs maintained WBV values below the ISO 2631-1 health caution zone.

“…Currently, the suspension mechanism is one of the most important elements of the car system, which primarily determines the safety of the car and driving comfort. The suspension system transfers and controls the force and reaction (static and dynamic) between the vehicle and the ground [2]. The suspension system is a system of springs, safeguards and associations between the vehicle and its wheels.…”

The driving comfort of the vehicle is primarily determined by the design of the suspension system, which transmits the force between the vehicle and the ground. There are different types of vehicle suspension systems, including active suspension systems that provide significant benefits for ride comfort while driving. However, the existing active suspension systems have limited functions such as power, and also complex structure. To overcome the problem, the proper design of the active suspension system by considering its present limitations is essential. A well-designed active suspension system controls the load on the wheels under the resonance of the body structure and ensures driving comfort. It reduces the vibrational energy of the vehicle body caused by the excitation of the road while keeping the stability of the vehicle within an acceptable limit. For a proper design of the active suspension system, the road surface, the seat suspension, and the wheel load are the most important elements to consider. In this study, different types of vehicle suspension systems with their limitations have been thoroughly investigated. Many aspects of control and some of the essential practical considerations are also explored.
