摘　　要：设计了含间隙的橡胶钢丝绳复合隔振器及试验过程,通过振动实验研究了该分段非线性复合隔振器的隔振性能。改变负载质量、激励大小、间隙值、橡胶材料等条件,研究了不同因素对隔振器隔振性能的影响。试验结果表明,随着负载质量和间隙值的增大,隔振器的隔振区间增大,隔振区内传递率降低;使用天然橡胶时,隔振器的隔振区间更大,且在共振区的振幅更小。该隔振器具有较大的隔振区间及较好的隔振性能,并能够在大振幅时增强钢丝绳隔振器的弹性支撑。A rubber and wire-cable composite vibration isolator and test process were designed, a series of experiments were done to study its isolation performance. Through changing load mass, the size of excitation, gap value and rubber material, the influence of different factors on performances of the vibration isolator was analyzed. The experimental results show that with the increase of load mass and gap value, the isolation bandwidth of the composite isolator is enlarged and the transmissibility is decreased. When natural rubber is used, the isolator has a larger isolation bandwidth and the amplitude is lower in resonance region. This composite vibration isolator has a large isolation bandwidth and a good performance in isolation region.
