This mechanical friction testing apparatus is designed to study the interaction of friction between two solid bodies under controlled conditions. The experimental unit ensures that the lines of action of friction and tensile forces remain parallel, enabling accurate and repeatable results. The system features a force gauge equipped with an air damper, which helps in reducing measurement spikes caused by slip/stick effects, thereby allowing for stable force readings. It includes three friction plates and two friction bodies, each offering different surface characteristics to analyze variations in frictional resistance. The normal force acting on the system can be modified by adding or removing weights, making it highly versatile for various testing scenarios. 2 driving velocities via a graduated cable drum. The apparatus is driven by a synchronous motor and a cable pulley system, allowing users to choose between two different driving velocities (23.5 cm/min and 47 cm/min). The friction body remains stationary, while the friction plate moves on a guided carriage, simulating real-world frictional interactions. Additionally, the air damper can be adjusted to either measure the mean friction force (with damping) or analyze slip/stick effects (without damping). The unit is supplied with a comprehensive storage system, ensuring all components are securely stored when not in use.
