Brake Squeal Analysis: Vibration with Complex Contact Conditions Brake discs develop large and sustained friction- induced oscillations, referred to simply as brake squeal, a challenging issue for engineers and researchers. Using ANSYS technology, you can analyze squealing via complex eigensolvers to identify unstable modes. Three different methods provide various levels of accuracy and computation speed by including various levels of pre-stress on the model. Campbell diagrams identify critical speed of rotating structures over a range of variations of a system's rotational velocity. Analysis of brake assembly for brake squeal: Combining nonlinear pre-stressing of structures and complex unsymmetric eigensolvers leads to accurate analysis. "The ANSYS environment represents a milestone in allowing simulation to be perceived as a standard and required activity in complex product development." Riccardo Testi CAE Analyst Piaggio & C. SpA Lufthansa Technik AG leverages ANSYS simulation software to gauge wear and tear of aircraft components. 6 https://www.randsim.com/structures
