Tautochronic centrifugal pendulum vibration absorbers: General design and analysis

摘要: Abstract Since the 1930s, centrifugal pendulum vibration absorbers have been used in rotating and reciprocating machinery for attenuation of torsional vibrations. A large variety absorber types were suggested design was done by linearization theory until introduction tautochronic bifilar absorbers. then, performance dynamic stability this specific type considered analytical numerical investigations. Different perturbations, e.g. nonlinear mistuning, order to optimize system performance, but characteristic remained unchanged. In paper, a general approach is proposed. As result, it possible deal with non-bifilar designs which provide application-related optimal resolve some existing limitations. Established analytic predictions that show satisfactory agreement as well experimental investigations are not applicable comparison different Therefore, second part work shows how analyze class using Hamiltonian formulation. Successive canonical transformations lead equations action-angle variables, then approximated first analyzed method averaging. These results basis analysis
