为了降低汽车燃料费、减轻汽车重量、提高盘簧的硬度和强度 ,日本对悬挂用盘簧进行了开发 ,制造出了 12 0 0ＭＰａ高强度弹簧钢———ＮＤ12 0Ｓ。为了便于开发和比较 ,采用了以高Ｓｉ-Ｍｎ系的ＳＵＰ7110 0ＭＰａ级的盘簧做比照实验。主要在三个方面开展了工作 :第一方面 :提
In order to reduce fuel costs for vehicles, reduce the weight of automobiles and increase the hardness and strength of coil springs, Japan has developed coil springs for suspension to manufacture a high-strength spring steel of 12 0 MPa - ND12 0S. In order to facilitate the development and comparison, using a high Si-Mn-based SUP7110 0MPa coil spring for comparison experiments. Mainly carried out in three aspects: First: mention
