摘要

为了降低贮运过程中的振动可能对导弹产生的损伤和危害,在隔振器中引入负刚度机构,拓宽振动的隔振频率,降低起始隔振频率,同时提出了一种非线性速度反馈控制的主动控制方法,用于抑制共振频率内可能产生的共振。研究结果表明,该隔振器有良好的低频振动抑制,高频振动隔离的效果,能够有效的降低振动对导弹的危害作用;采用线性速度反馈与立方速度反馈结合的方法,在有效抑制共振的同时,又降低了对非共振隔离的影响。

Abstract

In order to reduce the vibration and possible damage in the shipping process,introducing negative stiffness in the vibration isolator,broadening the vibration isolation frequency,reduce the starting vibration isolation frequency,at the same time,proposed a nonlinear speed feedback control method of active control is used to suppress resonance. the research results show that the vibration isolator has good low frequency vibration suppression,high frequency of the vibration isolation effect,it can effectively reduce the vibration harm of missile;Linear velocity feedback combined with cubic velocity feedback can effectively suppress resonance and reduce the effect of non-resonance isolation.
