新型耗能增强型SMA阻尼器设计和滞回耗能性能分析
Design and hysteretic energy analysis of new enhanced energy dissipation SMA damper
摘要
Abstract
The super-elastic deformation behavior of shape memory alloy was tested,and its stress-strain curves were equivalent to multi-linear model.A new enhanced energy dissipation SMA damper was proposed,and its structure,working principle,and design methods were introduced.The restoring force model formula of the damper was derived.A total of three analytical models were calculated by repeated low-cycle analysis.The results show that the hysteresis loop of the damper is fuller,and SMA cables of the damper show superior energy dissipation capacity.Therefore,the new SMA damper has a better value and prospects in engineering.关键词
