通常的粘贴型高温应变片,粘贴后,必须进行加热处理。因此,在大型结构情况下,或者由于加热,使结构变形或材料性能下降情况下,都不能对粘贴的应变片进行加热处理,致使热应力测量变得困难。本研究报告在提高测量精度的同时,在对应变片进行加热处理困难的结构上,也进行了应变测量方法的研究。这个方法是:在常温将应变片粘贴到试片上,放入加热炉内校正后,剥下应变片,再粘贴到结构上进行测量。在飞机那样的薄壁结构上也可以用,这一点已由实验确认。 The usual paste-type high-temperature strain gauge, after the paste, must be heat treatment. Therefore, in the case of a large structure, or due to heating, structural deformation or material properties decline, the bonded strain gauge can not be heat treated, resulting in thermal stress measurement becomes difficult. In this study, while improving the measurement accuracy, the strain gauging method was also studied on the structure which is difficult to heat the strain gage. This method is: at room temperature will be attached to the specimen strain gauge, into the furnace after correction, peel off the strain gauge, and then paste the structure to measure. It is also experimentally confirmed that thin-walled structures such as aircraft are also used.
