摘要

In this paper, by introducing elastoplastic shear layer, a new microslip model was presented to analyze dynamic response of system with dry friction damper under high normal force, full stick, paritial slip and full slip stage is considered when dry friction damper vibrates. Based on this model, vibration characteristic of dry friction damper was solved and analyzed by using equivalent linearization and first harmonic balance method. From results, some rules to reduce vibration are found, which can be used to guide damper design.
