摘　　要：通过圆环压缩实验方法对FV520B坯料与QT600-3材质在700℃、800℃、900℃时的摩擦系数进行了测定。通过FORGE仿真软件模拟圆环压缩实验获得的数据绘制了校准曲线,并进行了FV520B圆环与QT600-3砧板的压缩试验,将实验获得的数据与校准曲线进行了对比获得最终的结果:700℃时摩擦系数介于0.2~0.25,800℃时摩擦系数介于0.25~0.3,900℃温时摩擦系数介于0.3~0.35。In this paper,the friction coefficient between FV520B billet and QT600-3 material at 700℃,800℃and 900℃was measured by ring compression experiment.FORGE simulation software is used to simulate the data obtained from the ring compression experiment to draw the calibration curve,and the compression test of FV520B ring and QT600-3 cutting board is car⁃ried out.The experimental data is compared with the calibration curve to obtain the final result:The coefficient of friction is 0.2~0.25 at 700℃,0.25~0.3 at 800℃,and 0.3~0.35 at 900℃.
