Automatic Identification of Shaft Orbits of Hydraulic Power Sets

There is a large quantity of failure message in shaft orbits of Hydraulic power set, so it is essential to identify the shape of shaft orbits of hydraulic power sets. Hu's moment invariant and similarity judgment method are used to automatic identify the shape of shaft orbits. Work out the moment invariant of shaft orbits to be identified by using the improved algorithm, calculate the similarity between the shaft orbits to be identified and standard feature vectors by employing Euclidean distance, and then make a classification. A large number of simulation experiments show that it is feasible to adopt this method to make an identification of the shape of shaft orbits.
