Abstract: Force-displacement models for two Warrior Armoured Personnel Carrier track running gear rubber component are developed. The components are described by summing mathematical descriptions of their elastic response and viscoelastic response. The elastic response and the relationship between absolute displacement and viscoelasticity are determined by a novel method where the components are exercised at small amplitudes and various preloads. Viscoelastic response is described by nonlinear Maxwell elements. For simplicity |strain history dependent viscosity| is not described making the model a compromised: the response to sinusoidal displacement is reproduced with good accuracy but component|s response to dual-sine and stepped-displacement histories are approximated.

Keywords: military vehicles; rubber components; simulation; viscoelasticity; damping; elastomer; elasticity; force displacement models; Warrior armoured personnel carriers; track running gear; track bush material; carbon black filled natural rubber.
