By examining key locomotor parameters during terrestrial locomotion on a substrate without irregularities, we show that rats frequently accelerate and decelerate between two consecutive steps while maintaining an overall steady speed and that the touchdown order of contralateral limbs significantly influences those speed adjustments. The latter highly correlates with significant adjustments in ...

The aim of this paper is to obtain the strut friction–touchdown performance relation for designing parameters involving friction landing gear in a light aircraft. numerical model validated by drop test single half-axle gear, which used energy absorption properties process. Parametric studies are conducted using response surface method. Based on design experiment results and functions, sensitivi...

Due to their extensive use in various applications, helicopters need be able land a variety of conditions. Typically, helicopter landing gear system with skids or passive wheel-dampers is designed based on only one critical touchdown condition. Thus, this may not perform well different A magnetorheological (MR) dampers would promising candidate solve problem. However, semi-active controller mus...

In its natural habitat, Carausius morosus climbs on the branches of bushes and trees. Previous work suggested that stick insects perform targeting movements with their hindlegs to find support more easily. It has been assumed that the animals use position information from the anterior legs to control the touchdown position of the ipsilateral posterior legs. Here we addressed the question of whe...

The pull-in voltage instability associated with a simple MEMS device, consisting of a thin dielectric elastic membrane supported above a rigid conducting ground plate, is analyzed. The upper surface of the membrane is coated with a thin conducting film. In a certain asymptotic limit representing a thin device, the mathematical model consists of a nonlinear partial differential equation for the ...

Though the effects of imposed trunk posture on human walking have been studied, less is known about such locomotion while accommodating changes in ground level. For twelve able participants, we analyzed kinematic parameters mainly at touchdown and toe-off in walking across a 10-cm visible drop in ground level (level step, pre-perturbation step, step-down, step-up) with three postures (regular e...
