| Abstract: | This paper established the magnetic field calculation model based on the movement of piston ring and the actual size of the marine diesel engine, studied the influence on magnetic field output caused by the axial and radial movement of piston ring, and analyzed the correspondence between the output of magneto-resistive sensor and the rings wear. Signal has been measured with the magneto-resistive sensor that was installed in the marine diesel engines, which confirmed the correctness for the mathematical model. It provides a technological basis for on-line monitoring piston ring wear. |
