首次将轧制中的斜针测力原理应用于镦粗过程,制成了镦粗斜针测力器,研究镦粗圆柱体试样,沿按触表面半径,单位压力与单位摩擦力的分布。在计算中,考虑了测针与针孔壁间的附加摩擦力,以及测针端部凸出压板表面的高度对实测结果的影响,并分别进行了修正。 For the first time, the principle of inclinometer force measurement in rolling was applied to the upsetting process to make an upsetting incline needle dynamometer to study the distribution of the upsetting cylinder specimen along the contact surface radius, unit pressure and unit frictional force . In the calculation, the additional frictional force between the stylus and the pinhole wall and the height of the convex surface of the stylus at the end of the stylus are considered, and the corrections are respectively made.
