“…Semi-active and active vehicle suspension systems primarily use the following dampers: hydraulic dampers equipped with electro-valves (EMD), magnetorheological dampers for linear motion (MRD) and rotary motion (MRB) [ 9 , 10 , 11 , 12 , 13 ], electrorheological dampers (ERD) [ 14 ] and hydraulic and pneumatic dampers equipped with piezoelectric valves (PZD) [ 15 , 16 ]. Although solutions of this type have many advantages—such as the range of variation of the damping force—the use of magnetorheological fluid and standard solenoid valves results in relatively slow changes in damper characteristics over the full range, as slow as 80–100 ms [ 17 , 18 , 19 ].…”

In this paper, an original construction of a vehicle vibration damper controlled by means of a valve based on piezoelectric actuator is presented and investigated. The presented valve allows us to control dissipation characteristics of the damper faster than in other solutions adjusting the size of the gap through which the oil flows between the chambers of the damper. The article also presents the results of the experimental investigation of the above-mentioned damper showing the possibility of changing the value of the damping force five times in about 10 ms by changing the voltage supplying the piezoelectric actuator. Based on these results, dissipative characteristics were determined which enabled the identification of the parameters of the damper numerical model. The article also presents the results of numerical investigations a vehicle model equipped with the developed dampers. The results showed that the developed damper controlled by the use of the piezoelectric actuator can significantly affect vehicle traffic safety by reducing the variation of vertical forces acting on the wheels. The results obtained are so promising that the authors undertook preparations to conduct road tests of a vehicle equipped with the developed dampers.

“…On this basis, many semiactive control algorithms are based on SH control ideas, such as fractional SH, adaptive-SH [8][9][10][11], and gain-scheduled SH [12]. The SH control algorithm is simple to realize and has great practical application value [13]. The hybrid algorithm of SH-GH, which combines the operational stability of the GH algorithm with the ride comfort of the SH algorithm, was proposed and experimentally verified by Ahmadian et al [14,15].…”

This paper studies the semi-active suspension damping control algorithm. The shortcomings of traditional damping control algorithms such as the sky-hook algorithm and the acceleration-driven damper algorithms are analyzed in this article. For the shortcomings of the traditional damping control algorithm, a semi-active suspension damping control strategy based on improved particle swarm optimization is proposed. The proposed algorithm uses the dynamic nonlinear inertia coefficient instead of the fixed inertia coefficient of the traditional particle swarm algorithm, which improves solution efficiency and accuracy. Nonlinear damping curves for different forms of expression are optimized using the algorithm, and the optimal nonlinear damping curve for the white noise pavement is obtained. A simulation model is established to verify the effect of the proposed algorithm. The simulation results show that the nonlinear semi-active control strategy can achieve the target of high vibration isolation coefficient at high frequency and strong inhibitory resonance ability at low frequency. Moreover, the jerk of the spring mass does not deteriorate by a large margin. The results show that the nonlinear semi-active control strategy improves the driving comfort of the vehicle.INDEX TERMS Semi-active suspension systems, Improved particle swarm optimization, Hydraulic adjustable damper, Nonlinear damping.

“…More specifically, the first mode of CB vertical bending (VB), which occurs at a frequency of 6 to 12 Hz, has the greatest impact on ride comfort. Several research frameworks have been undertaken in recent years in an attempt to find various techniques for improving the ride comfort by doing relevant research in improving flexible vibrations of the CB using active [10] or semi-active suspension system [11]. However, the vibration and wave propagation, including the damping of the rails that support the traveling axles, affect the rail wheel interaction force.…”

A passenger railway vehicle’s lightweight design is an efficient technique of reducing energy consumption and dynamic forces between wheel and rail. However, light design results in resonant vibration in a car body. To restrain resonant vibration, a correlation between the suspended equipment variables and the car body’s modal frequency was investigated in this paper. A rigid–flexible general model was developed to examine the impacts of different equipment suspended under the chassis based on mass, location, and frequency on the car body mode. In addition, the numerical model is validated through the experimental result in terms of ride quality. The results demonstrate that the underframe equipment’s suspension characteristics have a significant impact on the mode of the car body, particularly the frequency of the first bending mode. Equipment with a considerable mass should be suspended near the center of the car body to optimize the frequency of the car body’s high-frequency bending. The weight of the equipment has a significant impact on the car body’s first bending frequency. The frequency of heavy equipment should be low enough to promote high-frequency transmissibility and improve the vibration characteristics of the car body.
