“…Their findings showed that a groundhook control can effectively reduce the dynamic load of tires and improve driving comfort. Yarmohamadi and Berbyuk 20 tested the control strategies of the semi-active suspension of a heavy vehicle; these strategies include groundhook, skyhook and groundhook–skyhook control strategies; the effect of a semi-active damper on vehicle dynamic performance was quantitatively displayed. Nicolas et al 21 expounded the application of a fuzzy logic method in a vehicle’s semi-active suspension and analysed its advantages over conventional control method.…”

A semi-active suspension variable damping control strategy for heavy vehicles is proposed in this work. First, a ninedegree-of-freedom model of a semi-active suspension of heavy vehicles and a stochastic road input mathematical model are established. Second, using a 1/6 vehicle as an example, a semi-active suspension system with damping that can be adjusted actively is designed using proportional relief and throttle valves. The damping dynamic characteristics of the semi-active suspension system and the time to establish the damping force are studied through a simulation. Finally, a variable damping control strategy based on an actuator motion state is proposed to adjust the damping force of the semi-active suspension system actively and therefore satisfy the vibration reduction requirements of different roads. Results show that the variable damping control suspension can substantially improve vehicle ride comfort and handling stability in comparison with a passive suspension.

“…The forces of interaction between the tires and the road surface induce stress on the pavement, which ultimately will lead to road failure [3] [4]. A fluctuating component of tire-road force is the main contributor to road damage along with other environmental factors [5].…”

Truck suspension system could reduce cab vibration as well as road damage. A number of methods are engaged to promote truck performance, such active and semi active control. With the purpose of reducing dynamic tire force, this paper presents a simulation analysis of a semi active suspension control for light-heavy duty truck, the controller scheme known as Ground Semi Active Damping Force Estimator (gSADE). A famous tire force control oriented algorithm for heavy vehicle suspension control known as Groundhook (GRD) also has been studied. Thus, the objective of this paper is to investigate the effectiveness of the gSADE algorithm compared to GRD and passive system. These algorithms are applied to a full light-heavy duty truck models, and the simulation model was developed and simulated using MATLAB Simulink software. Ride test was conducted using random road excitation at three different speeds, and the simulation results of gSADE, GRD and passive system are compared and analyzed. The simulation results showed that the gSADE control is able to reduced tire force significantly compared to GRD control and passive system.

“…In recent years, numerous axle suspension systems, especially the front independent suspensions, have evolved for heavy-duty mining trucks (HDMTs) to achieve an improved attenuation of WBV transmitted to the operator and to attain higher operating speeds (Azad and Khajepour, 2009;Timoney and Timoney, 2003;Yarmohamadi and Berbyuk, 2012). The ride dynamic performance of different off-road vehicle suspensions have also been investigated, which mostly focus on the energy-restoring and dissipative properties of the suspension while neglecting the contributions owing to suspension kinematics (Sun and Yu, 2005;Uys et al, 2007).…”

A variety of axle suspension linkage configurations with hydropneumatic struts are increasingly being used in mining trucks to achieve improved ride comfort and higher operating speeds. In this study, relative kinematic properties of four different independent front axle suspensions are investigated together with their effects on the handling dynamics of a mining truck. These included a composite linkage (CL), a candle (CA), a trailing arm (TA) and a double wishbone (DW) suspension. The kinematic responses are integrated to a handling model of a mining truck to study their relative handling characteristics. The results suggest that the CL and DW suspensions yield responses respectively during the steady-turn and lane-change manoeuvres compared with the CA and TA suspensions. The CL suspension may be considered desirable for future designs of high-performance trucks owing to its superior anti-roll performance under both steady and transient steering inputs. This paper is a revised and expanded version of a paper entitled 'Relative performance analyses of independent front axle suspensions for a heavy-duty mining truck' presented at SAE 2014 Commercial Vehicle Engineering Congress (COMVEC), Rosemont, Illinois, USA, 7-9 October, 2014.
