The article considers the change of radius instantaneous center rotation a car moving along curved trajectory during braking, taking into account lateral input wheels both axles cars, equipped with electronic tracking systems and not such. A criterion for assessing controllability cars on in braked state, by comparing ratio current speed to longitudinal base coefficients tire product car, mass ...

BACKGROUND The purpose of this study was to determine how a driver's foot and ankle forces during a frontal vehicle collision depend on initial lower extremity posture and brake pedal force. METHOD OF APPROACH A 2D musculoskeletal model with seven segments and six right-side muscle groups was used. A simulation of a three-second braking task found 3647 sets of muscle activation levels that re...

Abstract “An object remains in its state of rest or motion until and unless acted upon by an external force” Newton’s first law motion, Braking systems were made possible this rule Sir Isaac Newton, which states that the greater vehicle’s speed, brake force needed to slow it down. This idea spawned several studies subject braking, leading development, turn has given us luxury picking most effec...

AIM Despite numerous studies addressing the issue, it remains unclear whether the triceps surae muscle group generates forward propulsive force during gait, commonly identified as 'push-off'. In order to challenge the push-off postulate, one must probe the effect of varying the propulsive force while annulling the effect of the progression velocity. This can be obtained by adding a load to the ...

With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...

In this paper, a novel hybrid excitation linear eddy current brake is presented as a braking system for high-speed road and rail vehicles. The presence of the permanent magnets (PMs), whose flux lines in the primary core are oppositely directed with respect to the flux lines by the excitation windings, has the effect of mitigating the saturation of the iron in the teeth of the primary core. Thi...

The non-return mechanism is the key device that plays role of braking in opening-and-closing electric actuator an amphibious aircraft hatch door. ball-and-socket contact pair, providing pressing force, and multi-disc friction supplying torque, are two core components mechanism. In this paper, dynamic model established considering freedom rotation-translation. Based on MATLAB/Simulink, solution ...
