摘要
GB1972—80碟形弹簧受力分析与强度计算的数据和公式是引用了美国、日本弹簧设计手册中的数据和近似公式,误差较大。提出用修正系数η对近似公式进行修正,并给出精确解和有关计算图表。试验研究表明,采用国产60Si2MnA钢高温形变热处理工艺制造碟形弹簧,其机械物理性能可达到美、日同类钢种常规热处理工艺水平,GB1972—80的强度条件仍然适用。
The authors think there are errors in the data and equations for force analysis and strength calculation of disk springs in GB1972-80,suggest to revise the equations by using a revision coefficient η,and put forword accurate solutions and relevant diagrams and tables for calculation.Test and study show the disk spring manufactured with home-made 60Si2MnA steel by high-temperature ausforming provide preferable mechanical poprties.
