| 摘要: |
| 研制一种微型可调式黏滞流体阻尼器,提供可以调节的阻尼力。通过不同位移幅值、不同频率以及不同循环的加载试验,研究了可调式黏滞流体阻尼器的耗能参数和工作性能。同时,推导出阻尼力的理论计算公式,并与试验结果进行对比,结果表明:可调式黏滞流体阻尼器具有良好的耗能性和抗低周疲劳性能,理论计算与试验结果相近,表明文中提出的阻尼器具有较高的工作稳定性,且具有较好的密封性能。 |

| Abstract: |
| An adjustable and fluid viscous damper was invented in this paper,it can provide variable damping forces. Through the loading test of different displacement amplitude, various loading frequencies and cyclings, dissipating energy parameters and working properties of adjustable and fluid viscous damper were investigated. Meanwhile the theoretical formulas of damping force-displacement based on hydraulics were derived , and the experimental results were compared and analyzed. Results show that the invented viscous damper has a good performance of energy dissipation and a good low-cycle fatigue performance. The results of experiment are close to the theoretical calculation results,proving that the proposed damper has relatively high working stability and good sealing performance. |
