摘要
在铅挤压阻尼器耗能机理的基础上,对影响铅挤压阻尼器滞回性能的各种参数进行了数值模拟和试验研究.结果表明,挤压轴轴凸的长度和高度是影响铅挤压阻尼器阻尼力的主要因素;铅挤压阻尼器的滞回曲线饱满,是一种优良的耗能装置,可以用于工程结构的消能减震.
The numerical simulation and experiments of various parameters influencing lead extrusion damper are conducted based on the energy dissipation mechanism of a lead extrusion damper. The test results show that the length and the height of bulge are two important factors in yielding force of the lead extrusion damper. Furthermore,the hysteretic curve of the lead extrusion damper is chubby,and the lead extrusion damper is an excellent energy-consuming device and suitable for vibration control of engineering structures.
