一种小变形宽载荷适应性低频隔振器研究

Research on a low frequency vibration isolator with small deformation and wide load adaptability

针对载荷变化范围大、允许位移量小的特殊设备用隔振器设计难以兼顾小变形量和低固有频率的问题,通过两端叠加式弹性体结构设计,结合有限元仿真分析,提出了一种具备在宽载荷范围内保持较低固有频率和较小变形量的隔振器设计方案,并通过静、动态性能测试,验证了隔振器样机可以满足设计要求,证明了设计方案的可行性。该研究成果对载荷变化范围较大设备的隔振元器件设计有一定的指导意义。

It′s difficult to give consideration to both small deformation and low natural frequency in the design of vibration isolator for some equipment which require large load variation,small allowable displacement.Based on the two-stage superimposed structure design of the elastomer,and finite element simulation analysis,a design scheme of vibration isolator with low natural frequency and small deformation in a wide load range was proposed.Through static and dynamic performance tests,the proto vibration isolator could meet the design requirements,and the feasibility of the design scheme was proved.The research results can provide technical support for the design of vibration isolators for equipment with large load variation range.
