摘要
Abstract
This study employs numerical simulation methods to construct a simulation model of the hot spinning and pressure forming of TC4 titanium alloy gas cylinders,and the reliability of the model is verified through experimental validation.In thermal simulation experiments conducted at three strain rates of 0.1,1 s-1 and 10 s-1,the rheological stress distribution of TC4 material at temperatures ranging from 700 ℃ to 1 000℃is extensively investigated.Through comprehensive numerical simulation ana-lysis,the study delves into the influence of key process parameters such as forming temperature,spindle speed,and feed rate on the shaping of TC4 titanium alloy.Ultimately,a thermal spinning and pressure forming process for gas cylinders is formulated.The feasibility of the proposed process is further valid-ated through multiple iterations of TC4 titanium alloy hot spinning and pressure forming experiments.This research provides a scientifically sound and viable technological pathway for the manufacturing of TC4 titanium alloy gas cylinders.关键词
