一、前言液压式疲劳试验机亦称脉动千斤顶,是进行结构疲劳试验和研究的一项重要设备。我院结构实验室自成立以来一直没有购到。随着社会主义建设事业的发展,各种新结构不断出现,不少结构出现一些新的问题,迫切需要进行疲劳方面的试验研究,但因无此设备,所以无能为力,以致有的结构不得不运到北京或四川去试验。自文化大革命以来,在毛主席革命路线指引下,尤是是批林批孔运动的不断深入发展,我们狠批了林彪的“天才论”和孔老二的“上智下愚”等反动谬论,发动群众,破除迷信,解放思想,急社会主义建设事业之所急,决定自力更生,土法上马,群策群力试制 I. INTRODUCTION Hydraulic fatigue testing machine, also known as pulsating jack, is an important equipment for structural fatigue testing and research. Our structure laboratory has not been purchased since its establishment. With the development of socialist construction, various new structures have emerged and many structures have encountered some new problems. There is an urgent need for experimental research on fatigue. However, due to the lack of such equipment, there is no way to do so that some structures have to be transported. Go to Beijing or Sichuan to experiment. Since the Cultural Revolution, under the guidance of Chairman Mao’s revolutionary line, especially the continuous deepening of the Lin Shupai movement, we have approved Lin Shuo’s “Genius Theory” and Kong Laoer’s “Shangzhixiayu”. Other reactionary public opinion, the mobilization of the masses, the elimination of superstitions, the emancipation of the mind, the urgency of the socialist construction cause, the decision to rely on their own efforts, the use of indigenous methods, and concerted efforts
