Vehicle Suspension System

This paper deals with the active vibration control of a quarter-vehicle suspension system. Damping control methods investigated in this paper are: higher-order sliding mode control (HOSMC) based on super twisting algorithm (STA), first-order sliding mode control (FOSMC), integral sliding mode control (ISMC), proportional integral derivative (PID), linear quadratic regulator (LQR) and passive suspension system. Performance comparison of different active controllers are analyzed in terms of vertical displacement, suspension travel and wheel deflection. The theoretical, quantitative and qualitative analysis verify that the STA-based HOSMC exhibits better performance as well as negate the undesired disturbances with respect to FOSMC, ISMC, PID, LQR and passive suspension system. Furthermore, it is also robust to intrinsic bounded uncertain dynamics of the model.

Vehicle Suspension System

Because traditional passive suspension system can’t meet with the requirement of ride in all kinds of roads, elastomer damper was designed and installed on the limiting stopper of the suspension system. Two degrees of freedom model of suspension system with elastomer damper was built and its dynamics simulation was done by use of the software Recurdyn. The simulation results show that the application of elastomer damper can improve the ride of tracked vehicle; the striking force apparently decreases when suspension system has broken down and the probability of suspension system breakdown has been obviously reduced, all of which illustrates the elastomer damper has an obvious dampening effect on the tracked vehicle. Keywords: elastomer damper, tracked vehicle, suspension system, dynamics simulation

Vehicle Suspension System

Vehicle suspension system is an important part to minimize the vibration of the vehicle caused by road unevenness. Ideal conditions would be difficult to obtain, especially in rural areas with uneven road conditions. Analysis of passive suspension system in this study is expected to explain the level of comfort in riding Rural Multipurpose Vehicles. Full car modelling with 1 DOF riders used in this study, simulated using numerical simulation software. Excitation roads used in the form of a sinusoidal wave with an amplitude of 0.05 m and a wavelength of 0.5 m. Analysis carried out on the comfort of the vertical acceleration response received driver’s head. Based on the simulation results showed that by using a constant speed between 20-40 km / h, the vehicle will be comfortable driving for more than 2.5 hours.

This paper considers a new H2/GH2sliding mode control in controlling active suspension system subject to mismatched disturbance, without requiring a prior knowledge of disturbance. A quarter-car model is used in the study and the performance of the controller is compared with the existing passive suspension system. A simulation study is presented to prove the effectiveness and robustness of the proposed control method.
