In nuclear reactor engineering, the vibration of fuel element rod aud tube of heat exchanger is frequently induced by coolant flow. They always strike intermediate supporting baffles during their vibration. This kind of impact is intermittent and repeated. As a result, the wear and fretting of tube will be created and the damage would be caused finally. Therefore, it is very important to study dynamic effect of this impact. Recent years, the investigation for this problem has been made by some authors.The dynamic effects of impact for a tube with fixed ends against multiintermediate supports have been studied experimentally and analytically in this paper. The tested model is a stainless steel tube of 13.20 mm O. D., 10.20 mm I. D. and 1436 mm in length. Its ends are clamped. The baffles are simulated with support plates.Their number is up to three and their positions are adjustable. The rigidities of support plates are different. The clearances between the tube and plates are in the range from 0.20mm to1.00 mm. The tested tube is exited by unload The duration and number of times for impact, and time-history of response of the tube motion are recorded.The test results show the tube dominantly vibrates in the form of beam with single span, but the fundamental frequency is higher than its first natural frequency. The curve of the ratio of fundamental frequency of response to first natural frequency of beam vs. the ratio of initial displacement to clearance is given. Also the curve of the duration for contact with support vs. initial displacement-clearane ratio is obtained. The calculation is made by the theory of beam vibration. The analytical and experimental results are in good agreement. Many components of higher frequency are introduced into the response of motion. Their frequencies depend upon the position of support and their magnitudes are relative to intensity of impact. The linear spectrum of frequency for the motion response is given by Fourier Analysis.

本文以两端固支梁为模型,用分析和实驗方法討論了梁在自由振动过程中与带間隙的支撑碰撞的动力效应。目的是探討碰撞对梁的振动特性和振动响应的影响。实驗分別用了一个、两个和三个支撑板以及四种不同尺寸的支撑板,支撑板的位置是可調节的,支撑板与梁之間的間隙在0.25~1.00mm范围內改变。主要做了单边碰撞实驗,对双边碰撞实驗做了初步观察。实驗結果表明:梁的基阶振动頻率接近单跨梁的基阶固有頻率,但碰撞作用使基阶振动頻率明显地提高了。碰撞引起了許多高頻成分。最后,以梁中点初位移与間隙尺寸之比为参数給出了基阶頻率的变化曲綫,第一次碰撞开始的时間、第一次碰撞的持續时間的变化曲綫。对測得的位移响应时程曲綫进行了Fourier分析,并給出了离散譜綫。分析給出了中点有一个刚性支撑的碰撞結果,与测量結果符合良好。

本文用多次碰撞动力学模型描述快速氘原子D~*在碰撞中被冷却同时将CO_2分子振动、激发的过程。得到了振动激发的量子产额和第一次、第二次、第三次碰撞的关系。当D_2S与CO_2混合气中CO_2的浓度增加时,第二、三次碰撞的作用也增大。对于CO_2的v_3振动模,光解产生的D~*与CO_2的第一次碰撞形成CO_2分子的振动激发的假说是在实验误差范围内的。第二次碰撞对量子产额的作用小于第一次碰撞的1/10,第三次碰撞的作用小于第一次的1/100。可以忽略不计。对CO_2的v_2振动模,第二次碰撞对量子产额的作用在1D_25:4CO_2混合气中相当于第一次碰撞的1/4,第三次碰撞的作用相当于第一次的1/16。这些结果是与实验相符合的。并解释了量子产额在CO_2浓度增大时变大的原因。
