钎焊压力对GH4099蜂窝夹层结构焊接质量影响研究
Study on effect of brazing pressure on joining quality of GH4099 honey-comb sandwich structure
摘要
Abstract
Focusing on the manufacturing of GH4099 honeycomb sandwich structure,simulation analyses of stress and strain and brazing experiments about sandwich structure with different brazing pressures were carried out.Results show that there were stress concentrations in the contact area between honeycomb and plate and center of honey-comb core.With the increasing of brazing pressure,height deformation of sandwich structure increased and the joining quality was promoted.When the brazing pressure was increased to 0.1MPa,sandwich structure was almost fully brazed.To guarantee the brazing quality of sandwich structure and reduce thermal storage,the most suitable brazing pressure was set at 0.1 MPa,when the compressive strength of sandwich structure was 10.4 MPa.关键词
