【摘要】 半主动动力吸振器因其低能耗和宽的适用范围在许多振动控制中得到应用,通常采用的变刚度技术是决定其振动控制性能的关键。就现有的各种技术实现方式的原理、刚度变化范围、刚度相应速度和适用性等性能进行了分析和比较,特别是对其中重要性能进行了比较深入的分析,给出了综合评价,并提出的一种容易实现的变刚度装置。更多还原

【Abstract】 Semi-active dynamic vibration absorbers have been widely applied to control the vibration in dynamics for their obvious merits in cost,reliability and power consumption in comparison with the active absorbers.So far,to adjust the stiffness is the main technological measure which determines the performance of the absorber.This paper makes a survey on the research status of varied stiffness technologies with analysis of working principles and comparison of their performances in variant range of stiffness and responding speed as well as reliability.A varied stiffness device of simple structure is also presented.更多还原
