The static and dynamic properties of a vehicle suspension comprising hydraulic struts interconnected in the roll plane are investigated. The fundamental properties of the interconnected suspension are investigated and compared to those of the unconnected suspensions with and without the anti-roll bar, in terms of load-carrying capacity, suspension rate, roll stiffness as well as damping characteristics. The anti-roll performance of the interconnected suspension is analyzed for excitations encountered during directional manoeuvres. The ride quality performance is evaluated for excitations occur

Semi-active and active suspensions can improve both ride comfort and handling compared to passive suspensions. The authors have proposed a suspension comprising a pneumatic system capable of changing the stiffness of the suspension and a semi-active magnetorheological damper capable of controlling the suspension damping. Eight configurations of this magnetorheological/pneumatic suspension result from combining two possible stiffnesses (compliant and stiff) and four possible means of producing damping (constant low, constant high, on-off skyhook control and on-off balance control). The minimiza

Ambulance suspensions often give a poor ride, which may result in deterioration in the condition of ill or injured patients. Suspension of the ambulance stretcher itself is a lower cost option than a purpose- built ambulance suspension and may offer superior isolation of the patient from road-induced disturbances. This paper describes the development of a pneumatic stretcher suspension offering both pitch and heave isolation. Design and theoretical considerations are outlined, and preliminary performance figures reported. Subsequent parts of this paper will explore the dynamics of the system w

A shock absorber is a mechanical device designed to smooth out or damp a sudden shock impulse and dissipate kinetic energy. Without shock absorbers, the vehicle would have a bouncing ride, as energy is stored in the spring and then released to the vehicle, possibly exceeding the allowed range of suspension movement, Control of excessive suspension movement without shock absorption requires stiffer springs, which would in turn give a harsh ride. Shock absorbers allow the use of soft springs while controlling the rate of suspension movement in response to bumps. Now the project has mainly concen

In view of the deterioration of vehicle dynamic performance caused by the increased radial stiffness of a non-pneumatic wheel and its nonlinearity, a semi-active suspension error tracking backstepping control strategy based on the model reference method is proposed. Firstly, the segmental linearization of the nonlinear stiffness of the non-pneumatic wheels is carried out, and a quarter-vehicle system model integrating the non-pneumatic wheel and the semi-active suspension is established. Subsequently, a model reference system based on the H∞ control theory is designed. On this basis, a semi-ac

The use of a pneumatic spring suspension system in the second stage of spring suspension of high-speed rolling stock is an integral component of ensuring its permissible dynamic indicators and traffic safety indicators. This work is aimed at researching the deformation characteristics of the rubber-cord shell of the pneumatic spring in the vertical and horizontal directions, taking into account manometric pressure, external load and an auxiliary reservoir.

The object of this study is the pneumatic system in the spring suspension of rolling stock under conditions of high-speed movement from 170 to 250 km/h. Based on the thermodynamic model of the pneumatic spring suspension system, the influence of volume of the additional tank and the initial pressure in the pneumatic spring on the nature of change in the spring's dynamic stiffness, energy losses, and damping coefficient was studied. Based on the built "force-deformation" dependences for the pneumatic spring, it was established that the change in the volume of an additional tank has a slight eff

This paper has proposed a new hydro-pneumatic damper, allowing independent accumulator pressure compressibility from the chamber pressure which enhances isolation performances due its lower F-V hysteresis effect at moderate velocities. The system utilizes the generic hydraulic damper with two hydro-pneumatic accumulators and four check valves in its design. To evaluate the active suspension capability of proposed damper effectiveness, a 22-degrees-of-freedom (DOF), four-axle truck model is integrated with a hydraulic control valve, which is built in an LMS-AME sim environment.

The ubiquity of pneumatic vibration isolators, especially in heavy road vehicle suspensions and in passenger rail vehicle secondary suspensions, has boosted research interest in these systems. Thermodynamic models have been used in order to inform and support engineering design decisions. Most models assume that the air inside the system undergoes a polytropic transformation during the compression/expansion cycle, but the necessary polytropic index value is often guessed at and seldom measured. This paper presents measured polytropic indexes that contradict the traditional assumptions with res

A mathematical model of a pneumatic active car suspension system in a single wheel station form excited by realistic road roughness input is set up. The active control is exerted through a d.c. motor-driven air-pump. The model is used to show that essentially all the advantages of active control, within the terms of reference, are obtained by employing the control only at low frequencies and having the suspension parameters adapt to the running conditions as they vary. Control laws are derived using limited state feedback, linear stochastic optimal control theory and power consumption, and spa
