The purpose of this paper is to introduce a co‐simulation method to study the ground maneuvers of aircraft anti‐skid braking and steering.

Abstract

Purpose

The purpose of this paper is to introduce a co‐simulation method to study the ground maneuvers of aircraft anti‐skid braking and steering.

Design/methodology/approach

A virtual prototype of aircraft is established in the multibody system dynamics software MSC.ADAMS/Aircraft. The anti‐skid braking control model, which adopts the multi‐threshold PID control method with a slip‐velocity‐controlled, pressure‐bias‐modulated (PBM) system, is established in MATLAB/Simulink. EASY5 is used to establish the hydraulic system of nose wheel steering. The ADAMS model is connected to block diagrams of the anti‐skid braking control model in MATLAB/Simulink, and is also connected to the block diagrams of nose wheel steering system model in EASY5, so that the ground maneuvers of aircraft anti‐skid braking and steering are simulated separately.

Findings

Results are presented to investigate the performance of anti‐skid braking system in aircraft anti‐skid simulation. In aircraft steering simulation, the influence of two important parameters on the forces acting on the tires is discussed in detail, and the safe area to prevent aircraft sideslip is obtained.

Originality/value

This paper presents an advanced method to study the ground maneuvers of aircraft anti‐skid braking and steering, and establishes an integrated aircraft model of airframe, landing gear, steering system, and anti‐skid braking system to investigate the interaction of each subsystem via simulation.

Abstract

ALTHOUGH assisted by such agencies as aerodynamic drag and engine reverse thrust, slowing and stopping a modern aircraft on the ground is achieved principally by the use of wheel brakes to generate a horizontal drag force between the tyres and the ground. In the braking process the aircraft kinetic energy is converted to heat energy in the brakes by the application of hydraulic power to the brake discs to create friction. The heat energy is dissipated by natural or forced cooling.

The purpose of this paper is to realize a smooth and secure brake assistance system to avoid rear‐end collision of automobiles.

Abstract

Purpose

The purpose of this paper is to realize a smooth and secure brake assistance system to avoid rear‐end collision of automobiles.

Design/methodology/approach

It is important to judge necessity of deceleration assistance as early as possible and initiate the assistance naturally in order to reduce rear‐end crashes. However, it easily results in driver's discomfort. In addition, deceleration profile of the automatic braking is also important to realize smooth collision avoidance. In this paper, a deceleration assistance control for collision avoidance will be proposed based on the formulated braking behavior models of expert drivers to realize smooth, secure brake assistance.

Findings

The proposed brake assistance system can realize smooth deceleration profile and appropriate final status of the two vehicles for various approaching conditions. In addition, experimental results using a driving simulator will show validity of the proposed system based on subjective evaluation. It is also shown that the system realizes smooth deceleration control even under existence of the interaction between human driver and the system.

Research limitations/implications

This paper does not deal with effect of the deceleration method on change of drivers' behavior, including driver's trust on the system. Over‐trust should be eliminated if any.

Originality/value

The originality of the paper is to derive smooth secure collision avoidance system based on the driver's perceptual risk model. This method can realize smooth collision avoidance behavior for the various approaching conditions with a unified simple algorithm.

Abstract

This paper describes the operation of the Hytrol electronic/hydraulic anti‐skid system manufactured by Dunlop Aviation Division under licence from the Hydro‐Aire Division, Crane Corporation, Burbank, U.S.A. The first British aircraft to be fitted with this second generation anti‐skid braking system is the British Aircraft Corporation One‐Eleven 400 Series on order for American Airlines.

Abstract

ON the assumption that brakes are essential to the operation of modern aircraft, the question of design must be considered, and the exact functions must be studied with a view to obtaining the desired results. The chief requirements of ideal brakes may be summarized as follows:—

– The purpose of this paper is to study the influence of friction phenomenon generated by a disc brake on the dynamic behaviour of a one-stage spur gear.

Abstract

Purpose

The purpose of this paper is to study the influence of friction phenomenon generated by a disc brake on the dynamic behaviour of a one-stage spur gear.

Design/methodology/approach

A theoretical model is proposed and is based on both theories of Coulomb and Dahl in order to analyse the influence of disc brake friction phenomenon on the dynamic behaviour of one-stage spur gear transmission.

Findings

The influence of brake friction on the dynamic behaviour of the transmission is investigated using the proposed model and leads to observe higher vibration levels when the braking is occurring as well as the emergence of significant efforts at the gear teeth.

Originality/value

A new numerical model based on the implicit numerical integration technique of Newmark coupled with Newton-Raphson method is proposed to study the influence of friction phenomenon of a disc brake on the dynamic behaviour of one-stage spur gear.
