SAE no. 2 Model 1050 “Chase”

The Greening Model 1050Friction Material Test Machine is built to the specifications of SAE International’s J661 Brake Lining Quality Test Procedure, also known as the “Chase” test used for constant input friction force tests. Ideal for R&D work in friction materials including automotive brakes, clutches, truck brake blocks, and industrial friction materials.

The Model 1050 quickly and accurately measures effectiveness, fade, recovery, wear and speed sensitivity of brake and clutch friction materials. It generates automatic and real-time plots of friction and applied force, and test drum velocity and temperature. Heating and cooling curves are set automatically according to SAE J661 standards.

PERFORMANCE INERTIA BRAKE DYNAMOMETER

The model 1000/1250series dynamometers are designed for testing of braking systems for vehicle sizes ranging from motor bikes to commercial trucks. The dynamometers are equipped with a drive and a rotational inertia system to simulate deceleration and drag conditions, uphill or downhill grade effects, re-creation of hybrid or electric vehicle braking events, and other aspects of brake performance . These machines come with the latest control and data acquisition systems allowing the test engineer to quickly obtain accurate data on the performance of the brake assembly.

EventScan CAR

EventScan CAR is used to acquire brake performance data and to identify and analyze brake noise and vibration effects. It has been especially developed for in-vehicle tests on the road.

Extensive trigger options, fast trigger reactions, as well as high dynamic and precise speed, deceleration, and stop distance measurements allow to use the system for brake performance tests, like ECE R13, ECE R90 type approval, FMVSS 135, FMVSS 105, On-Brake DTV, ABS operational tests, and any special stop distance test, even with high initial speeds up to 300 km/h.

Sound, vibration, and other fast varying signals are synchronously acquired with present operating conditions of the brake (like brake pressure, lining or disc temperature, brake speed, torque etc.). Signals are collected by analog inputs, CAN bus connections, GPS sensors, tachometer pulse inputs, net- work connections, and other devices. All acquisition and analyzing tasks are performed online and in real time.

The system is compatible with all common brake noise test standards and it meets the requirements of the current EKB and SAE recommendations dealing with brake noise tests.

EventScan systems have been applied by leading US, European, and Asian car manufacturers and it is globally used by brake system suppliers, friction and damping material manufacturers.
