UMT Tribolab Mechanical Tester and Tribometer - Brochure

Bruker’s Universal Mechanical Tester (UMT) platform has been the most versatile and widely used tribometer on the market since the first model debuted in 2000. Now, newly designed from the ground up, the UMT TriboLab™ builds on that legacy of versatility with a unique modular concept that harnesses more functionality than ever before — all without any compromise in performance. In fact, the UMT TriboLab offers higher speeds, more torque, and better force measurement than any of its predecessors or competitors, plus it introduces powerful new features for improved efficiency and ease-of-use.

Brake Material Screening Module - Datasheet

The Brake Material Screening Module for the UMT TriboLab™ Mechanical Tester has been developed specifically for a wide range of pad materials qualification tests. During constant deceleration (stopping test) or constant speed (drag) testing, the module constantly monitors coefficient of friction (COF) between pad and rotor, while key parameters such as velocity, temperature, and contact pressure are controlled.

 

 

 

Application Notes

Brake Material Screening - (AN1013)

Using the UMT TriboLab it is now possible to test brake pad and rotor materials in real time and easily program industry-standard dynamometer protocols and standards, all while monitoring key parameters such as friction, temperature, sliding speed, and vibration. This application note describes the technique and demonstrates its very good correlation to tests executed on the full-scale dynamometer following the SAE J2522 standard (known as AK Master).

Evolution of OCP During Tribocorrosion - (AN1010) 1.4MB

This application note discusses how Bruker’s UMT TriboLab combines tribology and electrochemistry capabilities into one system to provide a better solution than traditional electrochemical measurements for tracking the evolution of OCP during a tribocorrosion test.

Understanding Engine Tribology: Performing Reciprocating Tests of Piston Ring and Cylinder Liner – (AN1011)

This application note discusses how it is now possible to perform standard tests for piston ring and cylinder liner frictional properties to assist automotive engineers, materials scientists, and lubricant manufacturers worldwide in the development of superior engine components and cost-effective lubricants.

Characterization of Lubricants for Research Development, Quality Control and Application Engineering - AN1000 1.6 MB

This application note provides an overview of lubrication science and engineering and then discusses the latest methods for comprehensively characterizing the performance of lubricants in nearly any application.

 Thin film and coating testing using the UMT testers - AN1001 2.3 MB

This application note discusses how the use of simultaneous measurements from integrated instrumentation has resulted in a number of interesting applications in the study of mechanical properties of thin films and coatings.

 Automotive Applications for Tribometers - AN1002 2.0 MB

This application note discusses a sampling of the many automotive component and material tests possible with a flexible, high-performance tribometer.

 Generating a Stribeck Curve in a Reciprocating Test - AN1004 620 kB

While classical Stribeck curve generation is done using a unidirectional test, it has been a challenge to obtain similar evaluations of lubricants and surface treatments using a reciprocating motion test. Bruker's Universal Mechanical Testers are equipped with high-speed linear oscillatory stages and adjustable stroke lengths and frequency ranges, as well as the measurement capabilities and companion software data reduction algorithms, to perform such characterization.
