无产阶级文化大革命以来,我们在毛主席“独立自主、自力更生”方针指引下,在各级党组织的领导和各兄弟单位的支持下,设计制造成功了4000马力内燃机车。其中柴油机的曲轴是采用钼铜合金球墨铸铁的,这是一个新生事物。为了进一步考核曲轴的安全可靠性,探索提高曲轴质量的新途径,厂党委决定对曲轴进行断裂力学的试验研究。这项工作经历了三个阶段。第一是学习运用阶段。我们坚持在干中学,学中干,在毛主席哲学思想的指导下,用断裂力学
Since the Great Proletarian Cultural Revolution, under the guidance of Chairman Mao’s principle of “independence and self-reliance,” we have designed and manufactured a 4,000-horsepower diesel locomotive under the leadership of party organizations at all levels and with the support of our fraternal units. One of the diesel engine crankshaft is made of molybdenum-copper alloy ductile iron, which is a new thing. In order to further test the safety and reliability of the crankshaft and explore new ways to improve the quality of the crankshaft, the factory party committee decided to test the crankshaft fracture mechanics. This work has gone through three stages. The first is to learn to use stage. We insist on doing middle school and doing middle school. Under the guidance of Chairman Mao’s philosophical thinking, we use the theory of fracture mechanics
