弹塑性接触冲击永久变形与滑移长度的解析求解OA北大核心CSTPCD
Analytical Solution of Permanent Deformations and Sliding Lengths during the Elasto-plastic Oblique Contact-impacts
在机械系统的设计与应用中,多体表面之间的弹塑性接触冲击现象是一个重要的力学问题,蕴含复杂的物理力学特性,对接触力等关键参数的解析与表征还存在许多争议与谜团.针对弹塑性倾斜接触冲击事件,根据Brake压陷模型建立瞬时接触力和接触变形的计算式,用接触变形系统地探讨与描述弹塑性接触冲击过程;基于广义动量定理,对冲击持时、永久变形和滑移长度的内在关系进行解析,分别得到以积分形式表示的永久变形和滑移长度表达式,再结合已发表文献中冲击对象在接触冲击前后的运动…查看全部>>
For the design and applications of mechanical systems,the elasto-plastic contact impact phenomenon among the multi-body surfaces was one of the key mechanics problems,which contained complex physical and mechanics properties.There still were many controversies and mysteries regard-ing the analysis and characterization of key parameters such as contact force.For the elasto-plastic ob-lique contact-impact events,the calculated formulas of instantaneous contact…查看全部>>
