Mixed Slip-Deceleration PID Control of Aircraft Wheel Braking System

IFAC-PapersOnLine, 2018
Abstract Aircraft antiskid braking system is designed to prevent the main wheels from locking and additionally seeking the optimal braking performance. Wheel deceleration is the traditional controlled target used in antiskid system, since it can be easily measured by angular velocity transducer. However the optimal target value is hard to find due to

Braking and propulsive impulses increase with speed during accelerated and decelerated walking [PDF]

Gait & Posture, 2011
The ability to accelerate and decelerate is important for daily activities and likely more demanding than maintaining a steady-state walking speed. Walking speed is modulated by anterior-posterior (AP) ground reaction force (GRF) impulses. The purpose of this study was to investigate AP impulses across a wide range of speeds during accelerated and ...

Method for determining the phases of the braking process from experimental data on braking deceleration

Journal of Physics: Conference Series
Abstract In the study of extreme vehicle braking processes, theoretical models are commonly used that assume the longitudinal deceleration changes follow strictly linear laws, with phase transitions represented by distinct breakpoints. However, experimental investigations reveal that the deceleration characteristics during such braking ...

Vibrational behaviour of braking deceleration in passenger cars during emergency braking in urban environment

Journal of Physics: Conference Series
Abstract This study investigates the dynamic behaviour of a vehicle during extreme braking events, focusing on the oscillations in braking torque generated by the braking system and wheels. These oscillations are transmitted through the suspension system to the vehicle structure, affecting the characteristics of the overall acceleration ...

Brake deceleration of cars with light luggage trailers

Transport Problems, 2012
This paper presents some aspects of employing measurements of deceleration for the technical analysis of the brake process of cars with light luggage trailers. The analysis of the deceleration enables to assess the technical state regarding traffic safety and it can also be used for analysing the course of traffic accidents.
