摘要 本文建立了换热器管两端弹支、中间支承板孔中悬浮的力学模型,把板孔间隙的作用归结为附加质量和附加阻尼、分析了管在多个中间支承板中悬浮时的固有频率和阻尼比,并在静水中作了对比测试。结果表明,计算值与试验值吻合良好. This paper sets up a model of a two-sides -elastic supported heat transfer tube suspending in the orifices of the supporting planks. The influence of the clearance between the orifices is due to the added mass and added damping. The natural frequencies and the damping ratio of a tube suspending in orifices of several supporting planks are analysed and experiments in still liquid are done. The result of calculation matchs the result of experiments quite well.
