Relative kinematic and handling performance analyses of independent axle suspensions for a heavy-duty mining truck

Abstract

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.

Solution of steering angle based on homogeneous transformation

“…Kim and Shin 11 built a kind of steering Pull Model which takes lifting force and torque caused by kingpin location and camber angle. Kang et al 12 calculated wheel alignment parameters and researched the handling stability effect of various types of suspension on heavy-duty mining truck. Mi et al 13 established a 5-degrees-of-freedom shimmy model of vehicle and derived tire–road constraint equations.…”
