Still, the tests identify, that in general, under fluid lubricant, high die surface hardens, low die surface roughness, high sheet surface roughness are favourable to lower coefficient of friction and decrease galling . It is of positive significanae to add extreme pressure additives and friction modifier into lubricants in order to improve the friction condition in deep drawing .

本文通过“带料弯曲拉伸试验机”校准确地模拟了08F薄板深冲的摩擦场。试验表明:在一定的材料付和润滑条件下,深冲摩擦系数与面压、变形速度、凹模圆角半径的变化服从μ_(SD)=KP_(SD)~mV_(SD)~nR_d~n关系式(式中K m、n、p为经验常数,且K>0,m、n、p均<0)。试验证实:采用流体润滑剂,模具的硬度高、模具表面粗糙度低、板材表面粗糙度高均有利于降低摩擦系数和减少“咬焊”现象的产生。在润滑剂中添加权压剂和摩擦稳定剂对改善深冲摩擦条件有积极的意义。

The N-S equations have been reduced to a set of three-dhnensional boundarylayer equations in an arbitrarily non-orthogonal-curvilinear rotating coordinate system by means of the order-of-magnitude analysis, and the effects of rotation on boundary layer are analyzed. A new pressure gradient iteration method is proposed to deal with the problem caused by nonzero normal pressure gradients. On the basis of BOX method, a numerical scheme and corresponding FORTRAN program are developed for solving the three-dimensional boundary layer with rotation. Three kinds of flow fields are calculated-rotating plate, helical blade, and compressor rotor blade. The results are compared with other researcher's calculation and experimental data. The comparison shows that the numerical method and program proposed in this paper are good, and can be used to simulate the three dimensional laminar and turbulent boundary layers on arbitrary objects with or without rotation. Finally, the authors have also investigated the effects of rotation (especially the normal pressure gradients) on boundary layer behavior on a rotating cylinder surface. The results indicate that the rotation effect is very important under certain conditions.
