八、变形力解析的切块法(Slab Methob)——主应力法切块法在苏联又称“主应力法”在日木又称“平均应力法”,早在本世纪二十到三十年代就用于分析拉拔、镦粗、挤压及轧制工序[1],是一个比较简明的分析接触面上正应力分布并计算平均变形抗力的一种方法,由于所推导出的公式能明显地(至少是定性地)说明各因素(摩擦、工件尺寸比、受力状态)对平均变形抗力的影响[2]、[3],所以至今仍然是变形力计算的重要方法之一[4][5],由于不同学
Eight, deformation force analysis of the method of cutting (Slab Methob) - the main stress method of cutting method in the Soviet Union, also known as the “main stress method” in Japan also known as the “average stress method”, as early as twenty to thirty in this century The age is used to analyze the drawing, upsetting, extrusion and rolling processes [1]. It is a relatively simple method to analyze the normal stress distribution on the contact surface and calculate the average deformation resistance. Since the formula Obviously, at least qualitatively, the influence of various factors (friction, work-size ratio, stress state) on average deformation resistance [2], [3] is still an important method of deformation force calculation [4 ] [5], due to different learning
