| 摘 要： | 基于电子信息设备等精密设备振冲防护中抗大冲击并兼顾衰减振动的要求,通过巧妙结合空气阻尼和油阻尼及橡胶元件和金属弹性元件,设计了结构微小的多介质耦合减振器原理样机.原理样机的多参数匹配试验研究表明它具有强非线性动态特征,在此基础上结合理论分析形成复合建模方法建立了样机非线性动态特性模型;此建模方法直接引入结构参数,为直接设计具体器件建立了理论基础.研究表明此多介质耦合减振器性能优越并具有良好的设计可控性;此方法还可以应用于其他减振器件研究和设计.

| Abstract: | A multi medium coupling shock absorber is designed by ingeniously coupling the air, oil, rubber and metallic elastic component to meet the requirement of resisting violent impact and attenuating vibration in the vibration impact safety device of electronic information equipment. The model machine shows strong nonlinear dynamic characteristics in the multi parameter coupling dynamic test. Based on this, the nonlinear dynamic characteristics model is established by combining the theoretical analysis and the actual structural parameters applied in modeling. The analytic result shows that the multi medium coupling shock absorber has a good dynamic performance and controllable design capability. The modeling method is applicable to the research and design of other shock absorbers |
