• Resumen

  • One of the most essential competencies that all mechanical engineers need to acquire during their studies is the ability to model and simulate problems and mechanical systems, in order to be able to predict the influence of parameter changes and optimise the solving of any problems. Simulation programs such as `Simulink' can be applied in Mechanical Engineering, not only as Design tools but also for Teaching. The Simulink models that have been developed to supplement theory classes can be at the students' disposal, so that they can check the influence of changes on different system parameters and properties. The theoretical study of the `stick±slip' friction phenomenon, which appears in some low-speed contacts, and its simulation using Simulink is presented. The influence of parameter changes is also presented and explained as an essential part of the Design Criteria. In the `Machine Vibration and Noise' course at Universidad Polite Âcnica de Madrid, several Matlab and Simulink simulators of real problems related to vibrations in machines or installations are being used as teaching tools. The `stick±slip' phenomenon simulator is detailed as an example.
