【摘要】 粘滞阻尼器阻尼力响应模型是分析其抗震性能的基础与依据,孔缩力是阻尼力的重要组成部分。针对双出杆孔隙式粘滞阻尼器,基于试验数据,利用二分法,提出了一种孔缩力公式,用于修正阻尼力理论模型,并进行试验验证。验证结果表明:修正后的阻尼力理论模型与试验结果吻合程度好,具有较好的准确度和较高的精度;孔缩力公式和修正后的阻尼力模型的运用能够缩短设计周期,降低成本,为阻尼器精确设计和快速研发提供依据。更多还原

【Abstract】 Force model of viscous damper is the basis of analyzing its performance,while the hole-dissipation force is an important part of this force model. Based on test data,theoretical formula for hole-dissipation force was set up. And damping force model was modified and verified. The tests and simulation results indicated that modified theoretical force model is correct,precision and fit with the experiments data. Application of this model can reduce the design period and decrease the cost.更多还原
