绕管式换热器管板应力的实验研究

Experimental Study of Tubesheet for Wrapped-Tuhe Heat Exchanger

采用组合式密封层和特制的引出导线密封装置，测定了在较高水压作用下的绕管式换热器的管板应力。测试结果表明，实验值与有限元计算值基本一致。

In the paper,the stresses in the tubesheet of wrapped-tube-exchangerwere measured using a combined sealed layer and a special manufactured out-wire sealedequipment under higher pressure water. The results show that the experimenetal dataare in agreement with the results of finite element method.
