摘　　要：为了提高隔振设备应对冲击的能力,开发了一种具有黏性阻尼器的隔振装置。黏性阻尼器受到外界冲击作用下趋势活塞运动,在孔缩效应趋势下形成的阻尼力使得冲击能量被耗散,进而实现隔振的目标。仿真分析结果表明:伴随阻尼孔尺寸的不断增加,阻尼力呈现逐渐减小趋势。当孔径尺寸从2 mm增加到3 mm时,阻尼力峰值急剧下降,体现出强烈变化特点。实验验证结果表明:伴随载荷提升,相对位移及加速度的误差都反映出单调增加的特征。在输入载荷低于60 g的条件下,仿真误差都在5%以下,仿真结果保持高度一致。该黏性阻尼器中减压阀能够避免出现阻尼力过大的问题,可以维持较强的性能,该研究为液压隔振装置理论研究奠定了良好的理论基础,可以拓宽到其它的减震领域。In order to improve the ability of vibration isolation equipment to cope with shock,a vibration isolation device with a viscous damper is developed.When the viscous damper is subjected to external impact,the piston tends to move,and the damping force formed under the trend of hole shrinkage effect dissipates the impact energy,so as to achieve the goal of vibration isolation.The simulation results show that the damping force decreases with the increasing of the damping hole size.When the aperture size increases from 2 mm to 3 mm,the damping force peak value decreases sharply,showing a strong change.The experimental results show that the errors of relative displacement and acceleration increase monotonically with the increase of load.Under the condition that the input load is less than 60 g,the simulation error is less than 5%,and the simulation results are highly consistent.The pressure reducing valve in the viscous damper can avoid the problem of excessive damping force and maintain strong performance.The research has laid a good theoretical foundation for the theoretical research of hydraulic vibration isolation device,and can be extended to other shock absorption fields.
