Optimization of parameters of Anti lock Braking System for use in deep drawing
Authors
Abstract:
A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the conditions of drawing and increasing LDR The results of steel sheet (ST14) with 0.5 mm thickness shows that for each velocity of punch there is an optimum frequency for ABS.The best condition for applying force of blank holder is create a constant gap and a variable gap with ABS system.

full textDesign of an anti-lock regenerative braking system for a series hybrid electric vehicle
In this paper, an adaptive rule based controller for an anti-lock regenerative braking system (ARBS) of a series hybrid electric bus (SHEB) has been proposed. The proposed controller integrates the regenerative braking and wheel anti-lock functions by controlling the electric motor of the hybrid vehicle, without using any conventional mechanical anti-lock braking system. The performance of the ...
full textHydraulic anti-lock, anti-skid braking system using fuzzy controller
To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...
full textdesign of a new anti-lock braking system for motorcycles
a new anti-lock braking system (abs) for motorcycles is proposed in this study. it functions by processing the speed of the motorcycle tire in contact with the ground relative to the speed of the motorcycle itself and by calculating the slip ratio (λ) of the tire slipping on the ground while braking, and reducing it to a minimum which leads to increased controllability of the motorcycle and red...
full textBicycle Anti-Lock Braking System Prototype Development
The passive and also the active safety systems of the vehicles evolved in the last decades. Beside the safety system of cars and trucks the smaller vehicles like the motorbikes, scooters, e-bikes and bicycle’s systems evolved as well. The aim of the project was to create and develop a prototype bicycle that uses a hydraulic type antilock braking system. The paper presents shortly the dynamics o...
