我所于今年四月七日至十二日在上海五七○三厂召开了振动消除应力技术座谈会。参加会议的有部属厂所十四个单位,部外厂校八个单位共四十八名代表。会上有十一个单位介绍了经验,并观看了五七○三厂振动消除焊接构件应力的现场表演。振动消除应力是项新的工艺技术。我部从一九七五年开始研究,近两年来,各飞机工厂和设计所在不同程度上应用于型架铸件、焊接件及其它构件,效果尚好。
On April 7 to April 12 this year, I held a symposium on vibration-dissipating stress technology in Shanghai No. 5703 Factory. Attend the meeting, there are 14 subordinate factory units, 8 factory units outside the school a total of 48 delegates. At the meeting, eleven units introduced their experiences and watched the live performance of the vibration at 5703 to eliminate the stress of welded structures. Vibration elimination stress is a new process technology. Since 1975, I started to study in my department. In the past two years, various aircraft factories and design institutes have used the castings, welded parts and other components to varying degrees and have achieved good results.
