Test Rig to Measure the Coefficient of Friction of Various Materials at Different Velocities and Pressures

Abstract: This thesis presents the design and development of a versatile test rig specifically tailored for measuring frictional properties of diverse materials across a wide range of velocities and pressures. The ability to accurately quantify frictional behaviour under varying conditions is essential for understanding material performance in numerous applications, such as automotive, aerospace, and manufacturing industries. The primary objective of this research is to design a test rig capable of simulating real-world operating conditions, facilitating the evaluation of frictional forces experienced by different materials. The experimental setup incorporates a carefully designed sliding mechanism, pressure control system, and instrumentation to measure frictional forces with high precision. The test rig's sliding mechanism is built to accommodate various material samples, allowing for controlled movement along different planes with adjustable velocities. By subjecting these samples to controlled loads, the influence of pressure on frictional behaviour can be systematically investigated. Moreover, the test rig features to replicate conditions encountered in practical scenarios. To ensure accurate measurements, the frictional forces are captured using high-resolution load cells and strain gauges integrated into the test rig. This thesis contributes to the field of material science and engineering by providing a comprehensive framework for evaluating frictional behaviour under controlled conditions. The developed test rig serves as a reliable and versatile platform for studying material performance, guiding the design and development of more efficient and reliable systems in numerous industrial applications.
