“…There were six (rather than 12) wobbling mass visco-elastic parameters, the horizontal and vertical stiffness and damping constants being set equal (equations (1) and (2)) in order to reduce the number of parameters. The visco-elastic parameter values were allowed to vary by 50% from initial estimates obtained from Gilchrist and Winter (1996) for the foot-ground interface parameters, and from trial simulations for the wobbling mass parameters. In addition there were 17 kinematic parameters which allowed small variations in the initial whole body orientation and angular velocity and the joint angle time histories of the ankle, knee and hip of the takeoff leg in order to compensate for errors in the digitised data.…”

“…The hydraulic unit is formulated as a highly nonlinear spring-damper element where the damping characteristics can be changed dynamically. The sound foot consists of four segments connected by revolute joints [3]. For the ground contact five nonlinear contact elements are used for each foot, two at the heel, two at the bale, and one at the first toe.…”

“…Multi-segment foot kinetics have also been estimated from measured kinematics using foot-ground contact models (Meglan 1991;Gilchrist & Winter 1996;Peasgood et al 2007;Jung et al 2014). However, published contact models remain in an early stage of development and there is no single accepted method for modelling the foot-ground interaction (Pàmies-Vilà et al 2014).…”
