近代动力机(柴油机、蒸汽轮机、燃气轮机等)正向着高速度和大功率方向发展,因此,各国对其振动结构件减振性(衰减性)的研究越来越广泛。我们在进行内燃机车生产时,由于多种中速大功率柴油机曲轴制造的需要,对有关材料、减振性的考查研究,被提到了日程上。但是,我们无论是设备条件或是技术力量都很差,困难很多。于是,我们带着这个问题学习了最高指示,毛主席说:“什么叫工作,工作就是斗争。那些地方有困难、有问题,需要我们去解决。我们是为着解决困难去工作、去斗争的。越是困难的地方越是要去,这才
Modern power machines (diesel engines, steam turbines, gas turbines, etc.) are moving toward high speed and high power. Therefore, the research on vibration reduction (attenuation) of their vibrational structures is becoming more and more widespread in various countries. When conducting diesel locomotive production, due to the need of manufacturing a large number of medium-speed and high-power diesel crankshafts, research on the vibration damping properties of materials was mentioned on the agenda. However, we have a lot of difficulties in terms of equipment conditions and technical capabilities. Therefore, we learned the supreme instructions with this question. Chairman Mao said: ”What is work, work is struggle. Where there are difficulties and problems, we need to solve them. We are going to work and struggle to solve the problems The more difficult the more places to go, this is
