1973年英国B ＆ S马赛工厂为了更好地了解该厂整体机身热模锻压力机(图1)的弹性变形情况,拟定了一项包括下述几方面的研究计划: 当把模具放在中心和偏心位置承载时,从理论上确定压力机处于弹性变形系统内的一些主要零件的应力值和变形量; 在静态和动载的情况下实测应变和变形量,以验证上述理论分析结果(图2); 设计并提供了一种精确、可靠的压力机负荷监测系统,以代替机械伸长式负荷指示仪。这一应力研究结果有助于对常规设计方法
1973 B & S Marseille, UK In order to better understand the plant’s overall hot forging die press (Figure 1) of the elastic deformation, developed a research plan that includes the following aspects: When the mold on The stress and deformation of some main parts of the press in the elastic deformation system are theoretically determined when the center and eccentric positions are loaded. The measured strain and deformation are measured under static and dynamic loads to verify the above theoretical analysis results Figure 2). An accurate and reliable press load monitoring system was designed and implemented to replace the mechanically extensible load indicator. The results of this stress study contribute to the general design approach
