| dc.description.abstract | An Oscillating Wear Tester (OWT) was built to simulate the piston-cylinder tribology in internal combustion engines. This tester consists of load system, motion system and frictional force measurement system. It operates at a speed of 10-1500 rpm. AL 380-0-F die casting alloy used as blank (cylinder) and stainless steel specimen slider was fabricated as a ring in piston ring assembly. Simulation for the spring strain plate, blank and base assembly was conducted to find the stress and deformation by using SolidWorks, CosmosWork software. Geometrical analysis for the motion of the specimen on the blank of OWT was conducted by using MATLAB software to find the mode of linear velocity at 750 rpm. Strain gauge was used to transfer the signal of the frictional force throughout the Amplifier to data acquisition (DAQ) and then to the computer with LabView software. OWT was used to verify friction and the wear processes. Many studies were conducted to find the relationship between the coefficient of friction (COF) with load, surface roughness (Ra) and time. The relationship between the wear with (Ra) and different quantities of oil was studied. The relationship between temperature with Ra, time and different quantities of lubricant was studied. From the results, it can be found that the COF decreases when the load increases. Besides, COF rises when Ra increases and fluctuates with time. The wear increases with Ra increases and decreases when the quantity of oil increases. Also, the temperature increases with Ra increases and decreases with oil increase. With the time, the temperature increases and after approximately 35 minutes, reached stability. All these results were acceptable . | en_US |
