This paper is one of the developments of our previous investigations (for 塑压接触面上之摩擦力,在一定时间作用于一定曲线族之切线方向,此曲线族称为“摩擦线”,其理论意义为:摩擦线本身为塑压表面流动之方向规律;其实际意义为:加工压力之科学计算有赖于摩擦线。在连续塑性变形过程中,接触面上质点之流动轨迹称为“长程滑线”,在塑压中一形状变为另一形状,长程滑线为始末形状间之表面变化规律。本支为一系列研究(例如[1]至[3])之续,目的及结果有三: (1)证明前文中摩擦线、等压线与压力布三个微分方程不受摩擦物理方程之约束; (2)提出椭圆板摩擦线族之另一解; (3)开拓出决定直观摩擦线的方法,定出塑泥及铅椭圆板之一系列摩擦线族,并对理论与实验结果作了比较讨论。金属摩擦线研究在进行中。北京钢铁学院的温金珂先生在本文前一作者指导下作过一长方板的摩擦线,她的结果将在长方板摩擦线系统化研究中一并发表。 文摘来源 The contact surface in plastic deformation is considered as a field, whose field-line is given by the "generalized rule of gradient" based upon the condition of least resistance applied both to effective and ineffective direction of "relative" slip on solid and liquid surfaces, as shown by equation (1),which is the formulation of the sta tement that the direction of field-lines is the direction of (most rapidly) decreasing frictional resistance [equation (2) ]. The main results are: 前文简略地提到塑压陡线规律。本文视最小摩阻条件所定义之塑压接触面为一曲面“流”场,旨在于提出此“最小摩阻场”之场线规律与场函数(摩擦应力τ,压应力ρ)规律。主要结果为: 推广前文之陡线规律于广泛情况,指出“摩擦场”与“滑质场”之基本区别在于前者为发散场,向外减阻;后者为收敛场,向内减阻。二者之复合场有“分水岭”,内场收敛,外场发散。金属表面之粘性粘着区须为一收敛场。陡线规律之库仑标量方程引出两重要推论: (1)摩擦力正比于压力之陡率(并给出比例函数之实例); (2)一切塑性压力分布皆为摩擦线弧长之函数,常含一指数项。这概括进现存不少特解。 由严格不滑动条件定出具体之粘着区域。 试图研究(τ,ρ)在应力圆中定义之“摩擦点”变化规律。以重叠应力圆法定出平面应变时此点之变域,说明在平压中摩擦系数不大时,压力约近于第一主应力。 本文仅涉及原则问题。场函数解法之一见作者另文。 文摘来源 In the recent years, the theory related to friction-lines has been independently developed both in Europe~[1] and here~[2-8], according the information~[1] reached the author in 1956. These investigations are based on the condition of least frictional resistance at a point. 塑压接触面之质点滑动线称“摩擦线”。滑动现象有两种基本类型,一为“长程滑动”,摩擦线为质点之长程连续轨迹,如抽拔,挤压,冲压等塑性过程中之滑动;一为“短程滑动”,质点仅在摩擦线上滑动一微小距离,如锻,轧,压力实验等过程中之滑动(小压缩时)。 过去对这两种滑动现象之规律未曾分别处理。本文将摩擦力接纯力学关系视为一切应力,即压应力p与摩擦应力τ,以边界平衡关系,相系于一应力函数F: τ=Fp, F=((l_1~2p_1~2+l_2~2p_2~2+l_3~2p_3~2)/(l_1~2p_1+l_2~2p_2+l_3~2p_3)~2)~(1/2) -1,p_1,p_2,p_3为内部主应力;l_1,l_2,l_3为p对p_1,p_2,p_3之夹角余弦。除视τ为p之函数τ=τ(p)外,对摩摩力之物理性质不作规定。 在此基础上,以住意质点滑动之最小摩阻功为基本条件分析滑向规律,一如任意质点滑动之最小摩阻力条件之于“陡线规律”。如此,则问题类于古典变分问题,变分方程引出两结论:在短程滑动中,滑向规律为已知之陡线规律;在长程滑动中为以下将提出之“等倾陡线规律”。并得到几个有关重要推论。 文摘来源 << 更多相关文摘
