摘　　要：针对一种基于特斯拉阀单向流通性的新型黏滞阻尼器,利用MTS landmark电液伺服试验系统对单双阀两种工况的阻尼器进行多振幅多频率循环加载;基于流体在特斯拉阀内的沿程损失建立理论模型,用MATLAB软件对新型阻尼器及传统孔隙式黏滞阻尼器进行仿真分析,分组讨论新型阻尼器的耗能减震性能。试验及仿真结果表明:新型阻尼器是一种无刚度的速度相关型阻尼器,试验值与仿真值基本吻合,较传统阻尼器减震性能突出;单阀阻尼器其性能受流体速度影响存在适用局限性,可通过调整阀门组数以调节阻尼器耗能性能。Aiming at a new type of viscosity-based adhesive damping device based on the Tesla valve unidirectional liquidity.The MTS landmark electro-hydraulic servo test system is used to carry out multi-amplitude and multi-frequency cyclic loading of dampers in two working conditions of single and double valves.The theoretical model was established by the losses in the Slawa.Using MATLAB to simulate the new type of damped and traditional pore-type viscosity,and discuss the energy consumption performance of the new type of damper.Tests and numerical simulation results indicate that the new type of damper is a rigid speed-related type of damping device.The test values are basically consistent with the simulation value,which is more prominent than the traditional damping shock absorption performance.Applicable limitations can be adjusted by adjusting the number of valve groups to adjust the energy consumption performance.
