Improvements in the instruments used to characterize the friction and wear phenomenon are required to enhance the effectiveness of the research method. In this project, our goal is to design and build an experimental platform that evaluates surfaces' frictional behavior will be designed. # Solution Overview Our solution is to build a modular friction test platform, which is capable of accurately measuring the friction, wear rate and contact behavior between surfaces of different materials. It will include high precision sensors, controllable condition system and data acquisition system and allows researchers to simulate a variety of different conditions (temperature, loads, velocity) # Solution Components ## Mechanical Body Systems The platform will be using a modular design, which allows easier maintenance and transportation. Its body will be able to be fixed on other platforms to reduce errors from vibration or movement. ## High Precision Sensors The platform will contain four main sensor types: - Force sensors for constantly detecting the friction force. - Displacement sensors for monitoring wear and deformation on the platform. - Temperature sensors for detecting the temperature. - Velocity sensors for monitoring the velocity of the loads. ## Controllable Condition System This system will control the conditions of the platform, and it also consists of several parts: - High precision motor drive system for controlled sliding speeds - Normal force application unit for applying controlled load on normal direction - Temperature control module for adjusting the temperature # Criteria for Success We will measure our success by examining multiple sample objects’ friction properties on the platform, and check if every component works well. If the results of our examination are near the true properties of samples (error < 5%), we call it success. |
