Study of Simulation Tester for Key Rubbing Pairs in Internal-Combustion Engine
A simulation tester was designed which could be used to simulate the wear and vibration of the key rubbing pairs in an internal-combustion engine, such as cylinder liner-piston ring, crankshaft and sliding bearings. Its pivotal innovation is that high pressure air was adopted to simulate the explosive pressure and pressure evolution in a cylinder to accord with the real conditions. Pressure sensors, vibration accelerations sensors, oil monitoring sensors and temperature sensors were installed at many points and directions on the tester support to form an on-line condition monitoring system via the developed software, which could simultaneously monitor the real-time wear and vibration condition for key rubbing pairs in internal-combustion engine. It is believed that the successful application of the tester for both tribological and dynamic characterization will be very significant to study the key rubbing pairs in internal-combustion engine.
