Simulator for testing an abs modulator

Abstract

A simulator for testing an Anti-lock braking system modulator capable of easily setting the yawing of a vehicle and disproportionate concentration of a vehicle weight according to the various vehicle weights and diverse road surface conditions has wheels rotated by compressively contacting flywheel pairs, a flywheel driving portion for transmitting and managing a driving force to the flywheels, rotation-speed sensors for monitoring the rotational speed of the wheels and flywheels, pneumatic cylinders installed to respective wheels for regulating a frictional force between the wheels and flywheels, a braking system for inciting a braking force to the wheels to which a modulator to be tested is mounted, a pneumatic pressure generating circuit for supplying a predetermined pressure to the braking system and pneumatic cylinder, and a controller electrically connected to the flywheel driving portion, rotation-speed sensors and pneumatic pressure generating circuit, in which the controller controls the flywheel driving portion to permit the flywheel pairs to have the identical or different rotational speed responsive to an input signal from the rotation-speed sensors, outputs a control signal to the pneumatic pressure generating circuit, provides the identical or different pneumatic pressure to the pneumatic cylinders respectively connected to the wheels, and operates the braking system.
