对TC4钛合金进行表面超声滚压处理,分析了主轴转速、进给量、静压力、滚压次数、振幅五个因素对表面残余应力的影响,并通过正交试验进行了参数优化。试验结果表明,TC4钛合金零件在USRP处理后,表面产生较大的压应力,压应力数值与处理过程中的静压力、滚压次数、振幅呈正相关,主轴转速和进给量选取过大或过小都会使得压应力数值下降。通过正交试验和极差分析可知,在影响表面残余应力的各项因素中,静压力和滚压次数影响最为显著,并通过优水平分析,筛选出了合理的工艺参数方案。
Abstract:In this paper,the ultrasonic surface rolling of TC4 titanium alloy was studied,and the effects of spindle speed,feed speed,static pressure,rolling times and amplitude,on the Surface rolling process were analyzed. The parameters were optimized by orthogonal test. The results showed that the surface of TC4 titanium alloy had a large compressive stress after USRP,and the compressive stress was positively correlated with the static pressure,rolling times and amplitude. At the same time,the spindle speed and feed rate were chosen too large or too small value,the compressive stress value was decreased. The results also showed that,the static pressure and rolling times had a significant effect on the surface residual stress. Through the analysis of optimum level,the reasonable technological parameter scheme was screened out.
