Analysis and Exploration of Riveting Process of Titanium Alloy Blind Rivet
Titanium alloy blind rivets are high-end fasteners for aerospace.In order to solve the problem that the strength match-ing relationship of titanium alloy blind rivets is not clear in the riveting process,the riveting process analysis method based on de-form software is studied.Based on the calibration of structure size and material parameters,the riveting process simulation model of blind rivets is established.By analyzing the variation law of riveting force in the riveting process,the variation range of riveting force is divided into four variation areas:sleeve influence area,drive ring fracture area,lock ring locking area and stem fracture area.The reasonable distribution of the four areas is to ensure the high success rate of titanium alloy blind rivets,which is an im-portant basis for research and development.By changing the material variable properties of each part,the influence of strength/strength distribution of each component of titanium alloy blind rivet on the peak value of four regions was further determined.The related research provides a technical basis for improving the riveting success rate of titanium alloy blind rivets.
