【摘要】 本文通过试验研究了并列弹性双圆柱体在均匀流场中的脉动压力及其动态响应，给出了双柱间距直径比T／D＝1．75，2．5，3．5和4．19×104＜Re＜9．1×104范围中柱表面脉动压力沿圆柱周向的分布以及脉动升力和阻力系数．试验结果表明，柱的振动对其脉动升力和阻力系数有明显的影响．更多还原

【Abstract】 The fluctuating pressure and the dynamic response of elastic circular twin-cylinders arranged in parallel are studied experirnentally. The distribution of fluctuating pressure around the cylinder circumference, as well as the lift and drag coefficients are given for space-diameter ratio T/ D = 1.75, 2.5, and 3.5, in the range of 4. 19×104< Re< 9.1 ×104. The test results show an obvious influence of the cylinder vibration on the lif t and dragcoefficients.更多还原
