Parameters design of smart spring vibration suppression system based on common point of amplitude frequency characteristic curve cluster

  • 摘要: 研究了无阻尼智能弹簧减振系统的一种参数设计方法.采用等效线性化方法将系统中的干摩擦阻尼等效成黏性阻尼,建立系统的数学模型,推导出无量纲化的振动微分方程,得到系统频响特性的解析解.对系统幅频特性进行了数值分析,结果发现:幅频特性曲线簇通过一个公共点,该公共点随质量比的增大向左偏移,随刚度比的增大向右偏移;系统存在一个最优控制参数值,使系统幅频特性曲线峰值最小,其随质量比的增大而减小,但不受刚度比的影响.根据公共点的性质,得到幅频特性曲线簇公共点对应的频率比、最优控制参数和最小振幅的计算公式.确定系统参数的选用原则与范围,并利用公共点提出智能弹簧减振系统参数设计的方法和步骤.
