从两个角度来了解一下振动时效原理

振动时(shi)效设备是指减(jian)少或减(jian)少铸件,焊(han)接零(ling)件,机加工(gong)(gong)(gong)零(ling)件等(deng)上的(de)(de)(de)(de)残余应(ying)力并(bing)确(que)保工(gong)(gong)(gong)件尺寸稳定(ding)性(xing)(xing)的(de)(de)(de)(de)设备。振动时(shi)效原理(li)是通过时(shi)效设备使(shi)加工(gong)(gong)(gong)后(hou)的(de)(de)(de)(de)工(gong)(gong)(gong)件产生共振。通过共振,一(yi)定(ding)量(liang)的(de)(de)(de)(de)振动能(neng)量(liang)传(chuan)递到工(gong)(gong)(gong)件的(de)(de)(de)(de)所有部分,从(cong)而在工(gong)(gong)(gong)件内(nei)(nei)部引起(qi)微观塑(su)性(xing)(xing)变(bian)(bian)形(xing)。变(bian)(bian)形(xing)的(de)(de)(de)(de)晶格逐渐恢复平(ping)衡状态,从(cong)而消除和(he)均匀化了工(gong)(gong)(gong)件内(nei)(nei)部的(de)(de)(de)(de)残余应(ying)力,防止了工(gong)(gong)(gong)件在加工(gong)(gong)(gong)和(he)使(shi)用(yong)过程(cheng)中的(de)(de)(de)(de)变(bian)(bian)形(xing)和(he)开裂(lie),并(bing)确(que)保了工(gong)(gong)(gong)件尺寸精度的(de)(de)(de)(de)稳定(ding)性(xing)(xing)。下面我(wo)们就从(cong)两个方面来了解一(yi)下。从(cong)宏观的(de)(de)(de)(de)角度分析(xi),振动时(shi)效会引起(qi)零(ling)件的(de)(de)(de)(de)塑(su)性(xing)(xing)变(bian)(bian)形(xing),减(jian)少并(bing)均匀化残余应(ying)力,并(bing)提高材料的(de)(de)(de)(de)抗变(bian)(bian)形(xing)能(neng)力。毫无疑问,这
