Friction is the result of complex interactions between contacting surfaces in a nanoscale perspective. Depending on the application, the different models available are more or less suitable. Available static friction models are typically considered to be dependent only on relative speed of interacting surfaces. However, it is known that friction can be(More)
This work presents a methodology identifying the increase of backlash amount in any type of gearboxes for a movable mechanical unit. No external sensor is required. A dedicated test cycle, of at least 4–8 seconds long, is run regularly on the axis under examination. The motion data, i.e. position, velocity and torque references is logged and stored(More)
This paper presents a data-driven approach to diagnostics of systems that operate in a repetitive manner. Considering that data batches collected from a repetitive operation will be similar unless in the presence of an abnormality, a condition change is inferred by comparing the monitored data against an available nominal batch. The method proposed(More)
