Research and investigation on dynamic performance and testing requirements of liquid viscous dampersMa Liangzhe, Cheng Yongqi(Beijing Qitai Vibration Control and Scientific Development Co., Ltd., Beijing 100037, China)

Abstract:The hydraulic viscous dampers, an efficient and important dissipation vibration energy devices, has been used widely in China. However, enough attention has seldom been paid to research its performance requirements, quality control and the dynamic tests. A brief introduction is given on the different types and the working principles of oil dampers as well as on the latest development of viscous dampers in US. It illustrates with example on the testing category of viscous dampers in!the US, namely, prequalification test, prototype test and quality control test. The large dynamic testing devices in the US are listed and the drop hammer test is introduced as an alternative test.
