压电陶瓷ansys分析.doc

你好，我正在做一个ANSYS的压电仿真的瞬态分析，我的问题是怎么在耦合的电极上加载正弦电压载荷？2010-09-09 16:012405401032 | 分类：电脑/网络 | 浏览2094次我的命令流：/filename,fengming/prep7et,1,plane42,1et,2,plane13,7,1MP,ex,1,9.8e10 !黄铜MP,nuxy,1,.32MP,dens,1,7500mp,dens,2,7750 !PZT材料密度mp,perx,2,919 !介电常数mp,pery,2,826mp,perz,2,919tb,piez,2 !压电常数tbdata,2,-5.3512tbdata,5,15.784tbdata,8,-5.3512tbdata,10,12.295tbdata,15,12.295tb,anel,2,0 !弹性常数tbdata,1,1.2035e11,7.509e10,7.5179e10tbdata,7,1.1087e11,7.509e10tbdata,12,1.2035e11tbdata,16,2.1053e10tbdata,19,2.1053e10tbdata,21,2.2584e10k,1,0,0 !建模k,2,1e-2,0k,3,1.5e-2,0k,4,1.5e-2,1e-4k,5,1e-2,1e-4k,6,1e-2,2e-4k,7,0,2e-4k,8,0,1e-4l,1,2l,2,3l,3,4l,4,5l,5,6l,6,7l,7,8l,8,5l,8,1l,5,2al,1,10,8,9al,2,3,4,10al,5,6,7,8type,1mat,1mshape,0,2Dmshkey,1amesh,1,2type,2mat,2mshape,0,2Dmshkey,1amesh,3nsel,s,loc,x,1.5e-2 !位移约束d,all,ux,0d,all,uy,0/solu !瞬态分析antype,transtrnopt,fulltintp,0.25,0.5,0.5outpr,all,alloutres,all,allkbc,1nsel,s,loc,y,1e-4 !耦合电压cp,1,volt,alld,all,volt,0*do,i,1,50,1t=i/400000time,tnsubst,1v=40*sin(2*3.14159*42881*t)nsel,s,loc,y,2e-4cp,2,volt,alld,all,volt,vsolve*enddofinish这样加载问题在哪里，对不对？谢谢分享到：2010-09-09 18:30提问者采纳我先看看然后晚上回复你！方法是对这呢，不过在写程序的过程出现了一些小失误你看下我这样改下可以不？与你表达的意思是一致的，只是后面的东西有些改正，前面的材料以及模型尺寸楼主你就自己拿捏一些精度与单位就可以了allsel,allfinish/solu !瞬态分析antype,transtrnopt,fulltintp,0.25,0.5,0.5outpr,all,alloutres,all,allkbc,1nsel,s,loc,y,1e-4 !耦合电压cp,1,volt,allnsel,s,loc,y,2e-4cp,2,volt,allnsel,s,loc,y,1e-4d,all,volt,0allsel,all*do,i,1,50,1t=i/400000time,tnsubst,1v=40*sin(2*3.14159*42881*t)nsel,s,loc,y,2e-4d,all,volt,vallsel,allsolve*enddofinish提问者评价太谢谢你了，对了的，没有警告了！来自：求助得到的回答asel,s,56 ！选择面736cp,1,volt,all ！为该表面施加耦合电压 *get,n1,node,num,min ！定义该表面电极节点d,n1,volt,0 ！加0v电压ALLSEL,ALL ！选择全部asel,s,896 ！选择面896nsla,s,1 ！
