摘要
振动控制是关系到设备安全的重要问题,随着科技的发展,隔振显得越来越重要。有效的减小振动带来的危害,是振动控制研究的重要课题。通过正负刚度并联的原理,可使得系统的总刚度在平衡点附近趋近于零,从而可以有效降低系统的固有频率,实现低频隔振。本文建立了正负刚度并联结构的模型,并对其行了仿真,证明采用设计的模型可以有效实现低频的微幅隔振。
Vibration control is important to the equipment safe.With the development of technology, isolation is becoming more and more significant.Reducing the vibration and its baneful results is an important vibration research subject. By combining the positive stiffness and negative stiffness in parallel,the stiffness of the system tends to zero nearby the balanced point,which can effectively reduce the natural frequency of the system and realize the low fre- quency vibration isolation.This paper establishes the model of combining the positive stiffness and negative stiffness in parallel,and the simulation shows that the model can effectively realize the low frequency of micro vibration isolation.
