Parameters Analysis of Residual Stress Induced by Laser Shock Processing
, 2010 考虑激光冲击强化后塑性区深度及最大残余压应力的影响因素和影响规律问题,运用量纲分析的方法获得了影响冲击强化效果的主控因素,并给出了塑性区深度及最大残余压应力与峰值压力、压力持续时间、光斑半径的关系;利用基于LS-DYNA的二维轴对称有限元模型,计算了不同参数条件下金属靶体受冲击载荷作用的动态响应.计算结果表明,塑性区深度与压力持续时间成正比;最大残余压应力与压力持续时间无关;一定光斑半径范围内,塑性区深度及最大残余压应力与光斑半径无关;峰值压力超过一定值时 ...

接触网覆冰严重影响电气化铁路的受流质量与运行安全,机械除冰是目前应用最广泛的手段,实际作业中除冰装置沿接触线连续移动并施加间歇性冲击,而现有研究多局限于定点冲击模式,难以准确解释除冰机理.本文提出一种移动冲击载荷作用下覆冰接触线机械除冰建模及响应分析方法,通过建立覆冰接触线精细化有限元模型,以拉伸破坏准则定义覆冰材料侵蚀失效,采用LSDYNA非线性有限元显示动力学分析实现冲击载荷作用下接触线除冰过程中的模拟,重点研究除冰过程中的波传播规律,探讨了应力波叠加效应与覆冰破坏模式的关联性 ...
