1) upsetting
墩粗
1.
With the analysis method of contact mechanics in the elasticity mechanics, the causes to the axle end upsetting in the process of wheel disassembling are analyzed, and the following conclusions are obtained: In disassembling of wheels, if the compression is very great and applied directly upon the axle end, the possibility of axle end upsetting cannot be eliminated.
运用弹性力学中的接触力学分析方法 ,分析了解轮过程中车轴轴端墩粗现象的原因 ,得出如下结论 :当解轮时的压退力很大且直接作用于轴端时 ,就不能排除轴端墩粗的可能性。
2) mushrooming deformation
墩粗变形
1.
In order to investigate the coupling effect between the projectile deformation a nd the target, the mushrooming deformation of the projectile impacting on a defo rmable target was theoretiallly analyzed by taking into account the penetration of the projectile into the deformable target.
为了研究弹体撞击靶板过程中的弹靶变形耦合效应 ,在考虑靶板变形的同时 ,对柱形平头弹体的墩粗变形进行了理论分析 。
