Abstract:

Based on the bi-fold line hysteresis model, the mechanical analysis and reasonable simplification of a coated pipeline damping structure were done to establish its appropriate mechanical model. The mechanical model of a single-DOF hysteretic system was linearized equivalently using the equivalent linearization method to analyze the variation law of metal rubber's stiffness and damping with variation of excitation force, and conduct test verification. Meanwhile, the characteristic quantity was proposed to characterize damping performance of a coated pipeline damping structure. Variation laws of a metal rubber coated pipeline damping structure's damping characteristics with variation of its forming density, number of coated layers and magnitude of excitation were studied with tests to provide theoretical and test bases for vibration reduction engineering application of pipeline systems. © 2019, Editorial Office of Journal of Vibration and Shock.
