A simple model of compressor main bearings was evaluated using the mobility method. The model allows for the simulation of the three loading conditions of the compressor, as well as accounting for the geometry of the connecting rod and crankshaft. The simulation was then compared against the results from measuring the orbit of the crankshaft. This is a simple and low cost way to monitor the main bearings without installing sensors directly into the bearing sleeve. The results show good qualitative agreement to move forward with developing the model and sensor application with the end goal of application to health monitoring.
