水平分模平锻机大拉杆的大头采用了组合式浮动轴瓦,即孔与轴为大间隙配合(参见《重型机械》1984第7期)。本文介绍用数学公式表示贴合角度,可便于优选轴与孔的间隙及大拉杆的优化设计。并且通过广义座标中平面等参数有限元计算公式和最小二乘法求单元节点的应力公式,来计算接触应力并得到应力分布,简便可靠,有实用价值。供参考。 Horizontal split forging machine big rod with the bulk of the combined use of floating bearing pad, that is, the hole and the shaft for a large gap (see “Heavy Machinery” 1984 Issue 7). This article describes the use of mathematical formulas that fitting point of view, can facilitate the optimization of shaft and hole clearance and big rod optimization design. In addition, the contact stress and the stress distribution can be calculated by finite element method and least square method of generalized coordinate in plane and so on. It is simple and reliable and has practical value. for reference.
