In ANSYS Release 9.0, how can you obtain the total amplitude from a harmonic analysis?
|
In a harmonic analysis, the real and imaginary results are stored. The total amplitude is the SRSS of the real and imaginary amplitude. The HRCPLX command can be used to calculate the total amplitude for any frequency. Below is a test case for a cantilever beam. /prep7 et,1,182 mp,ex,1,10e6 mp,prxy,1,.3 mp,dens,1,.283/386.4 rect,0,10,0,1 esize,.5 amesh,1 nsel,s,loc,x,-.01,.01 d,all,all,0 alls fini /solu antype,modal modopt,lanb,1 save solve fini /solu antype,harm dmprat,.01 nc = node(10,0,0) f,nc,fy,10 alls hropt,msup harfrq,197,199 nsubst,2 kbc,1 outres,all,all solve fini /solu expass,on numexp,all,,,yes solve fini /post1 /com, **** REAL PART *********** nsel,s,node,,nc set,,,,,,,1 /com, **** IMAGINARY PART ****** prnsol,u,y set,,,,,,,2 prnsol,u,y /com, ******** TOTAL *********** hrcplx,1,1,360 prnsol,u,y |
