The rotary test is a popular method for assessing friction

The 6D Force-Torque Sensor works perfectly with the existing UMT TriboLab setup, ensuring smooth integration into previous experiences. The sensor is a plug-and-play device that can be paired with the quick exchange kit (AM30C413), fast exchange plate (M30C784), and 2-inch or 4-inch extension blocks (M30C366-1, M30C366-2).

A variety of upper specimens can be utilized with this setup to accommodate a wide array of test conditions and applications.

Bruker’s UMT TriboLab represents a cutting-edge modular platform featuring a single high-torque motor integrated into the base, enabling a broad spectrum of speed and torque testing.

Together with the advanced 6D Force-Torque Sensor, the TriboLab offers intricate motion and highly accurate measurements across multiple axes, which are essential for tribology research and industrial uses.

Rotary Test

The rotary test is a popular method for assessing friction and wear in laboratory settings and various industries. During the test, a ball or pin is positioned beneath the 6D Force-Torque Sensor, while a standard disk serves as the lower specimen (see Figure 8a/b).

In this setup, forces and torques across different axes are recorded to determine the friction coefficient and torque coefficient.

The combination of TriboLab and the 6D Force-Torque Sensor effectively harnesses the forces at the contact surface, minimizing the torques endured by the sensors and greatly reducing measurement uncertainties. According to Table 2, the average full-scale error recorded on the 6D Force-Torque Sensors was under 2%.
Measurements taken across various dimensions are invaluable for understanding the friction and wear characteristics of a tribosystem. The coefficient of friction measured in situ accounts for both Fx and Fy contributions, expressed by the formula COF=√(Fx² + Fy²)/ Fx.

During high-speed rotational tribological tests, any unwanted movements of contact partners due to loose assembly or breaks can negatively affect the outcomes. The 6D Force-Torque Sensor empowers users to detect such problems by monitoring torque output on the x and y axes in real-time (refer to Figure 8c), facilitating immediate resolution of issues.
