基于潜高斯过程引入理论先验的钛合金结构件残余应力场推断方法OACSTPCD
Inference Method for Residual Stress Field of Titanium Alloy Parts Based on Latent Gaussian Process Introducing Theoretical Prior
残余应力(Residual stress,RS)是导致钛合金结构件加工变形的主要原因.钛合金结构件的残余应力包括初始残余应力(Initial residual stress,IRS)和加工表层残余应力(Machined surface residual stress,MSRS),其中,MSRS是加工表层区域的IRS与高水平的加工残余应力(Machining-induced residual stress,MIRS)耦合作用的结果.结构件的加工变形…查看全部>>
Residual stress(RS)within titanium alloy structural components is the primary factor contributing to machining deformation.It comprises initial residual stress(IRS)and machined surface residual stress(MSRS),resulting from the interplay between IRS and high-level machining-induced residual stress(MIRS).Machining deformation of components poses a significant challenge in the aerospace industry,and accurately assessing RS is crucial for precise prediction and c…查看全部>>
