1.前言全预应力轧机是根据一种新的构思设计制造的轧机,它不仅大大提高了机座的刚度,而且明显地减轻了轧机的振动,为拓宽预应力轧机的效能展示了广阔的前景。针对设计制造的样机,测试了其振动烈度,全预应力轧机振动品质达到了ISO3945—1977标准规定的良好水平。下面从理论上分析全预应力轧机的减振机理,从而说明新设计思想的合理性。 1. Preface The prestressing mill is designed and manufactured on the basis of a new concept. It not only greatly increases the rigidity of the machine base, but also obviously reduces the vibration of the rolling mill. It also shows a great prospect for broadening the performance of the prestressing mill . According to the prototype designed and manufactured, its vibration intensity was tested. The vibration quality of the fully pre-stressed rolling mill reached the good level stipulated in the ISO3945-1977 standard. The following is a theoretical analysis of the damping mechanism of full prestressing mills to illustrate the rationality of new design ideas.
