槽式太阳能ansys建模的接触问题
|
槽式太阳能的支撑架和壳体我是一起建的模，有几个接触的地方我是用的共用节点，但支撑架支撑壳体的地方没有设置接触，也不知道怎么设置，得出的结果图就不合实际，望哪位高手指点指点，谢谢。。。 finish /clear *SET,Pin_number,8 *SET,Grid_degree,5 *SET,Length_total,12.000 *SET,a,5.760 *SET,f,1.710 *SET,b,1.500 *SET,ll,0.030 *SET,hh,0.030 *SET,k_point1_x,0 *SET,k_point1_y,k_point1_x**2/(4*f) *SET,k_point2_x,a/8 *SET,k_point2_y,k_point2_x**2/(4*f) *SET,k_point3_x,2*a/8 *SET,k_point3_y,k_point3_x**2/(4*f) *SET,k_point4_x,3*a/8 *SET,k_point4_y,k_point4_x**2/(4*f) *SET,k_point5_x,4*a/8 *SET,k_point5_y,k_point5_x**2/(4*f) *SET,k_point6_x,b/2 *SET,k_point6_y,0 *SET,k_point7_x,b/2 *SET,k_point7_y,-b *SET,k_point8_x,0 *SET,k_point8_y,-b *SET,k_point9_x,k_point7_y*(k_point7_x-k_point5_x)/(k_point5_y-k_point7_y)+k_point7_x *SET,k_point9_y,0 *SET,mm,a*(k_point5_y+b)/(a-b)-2*b*k_point3_y/(a-2*b)-k_point5_y *SET,nn,(2*k_point5_y+2*b)/(a-b)-4*k_point3_y/(a-2*b) *SET,k_point10_x,mm/nn *SET,k_point10_y,4*(k_point10_x-0.5*b)*k_point3_y/(a-2*b) /prep7 ET,1,BEAM188 MP,EX,1,2.1e11 MP,PRXY,1,0.3 MP,DENS,1,7850 SECTYPE, 1, BEAM, RECT, , 0 SECOFFSET, CENT SECDATA,ll,hh, ET,2,SHELL181 MP,EX,2,0.7e11 MP,PRXY,2,0.2 MP,DENS,2,2500 SECTYPE,2,SHELL, SECDATA, 0.004,1,0.0,3 SECOFFSET,MID k,1,k_point1_x,k_point1_y k,2,k_point2_x,k_point2_y k,3,k_point3_x,k_point3_y k,4,k_point4_x,k_point4_y k,5,k_point5_x,k_point5_y k,6,k_point6_x,k_point6_y k,7,k_point7_x,k_point7_y k,8,k_point8_x,k_point8_y k,9,k_point9_x,k_point9_y k,10,k_point10_x,k_point10_y spline,1,2,3,4,5 LSTR,1,6 LSTR,6,7 LSTR,7,8 LSTR,6,9 LSTR,6,3 LSTR,3,10 lstr,3,9 LSTR,9,7 lstr,9,10 lstr,10,5 Length_single=Length_total/(2*Pin_number) LGEN,2,ALL,,,,,-Length_single NUMMRG,KP NUMCMP,KP NUMCMP,LINE lstr,7,17 lstr,6,16 lstr,5,15 lstr,4,14 lstr,3,13 lstr,2,12 lstr,1,11 LGEN,2,ALL,,,,,-Length_single NUMMRG,KP NUMCMP,KP NUMCMP,LINE ADRAG,1,2,3,4,,,35 NUMMRG,KP NUMCMP,KP NUMCMP,LINE AGEN,2,ALL,,,,,-Length_single NUMMRG,KP NUMCMP,KP NUMCMP,LINE LSYMM,X,ALL ARSYM,X,ALL NUMMRG,KP NUMCMP,KP NUMCMP,LINE lstr,7,16 lstr,16,27 lstr,36,43 lstr,43,52 LGEN,Pin_number/2,ALL,,,,,-2*Length_single AGEN,Pin_number/2,ALL,,,,,-2*Length_single NUMMRG,KP NUMCMP,KP NUMCMP,LINE LSYMM,Z,ALL ARSYM,Z,ALL NUMMRG,KP NUMCMP,KP NUMCMP,LINE AATT,2,,2,0,2 MSHAPE,0,2D MSHKEY,1 AMESH,ALL LATT,1,,1,,,,1 SMRT,Grid_degree LMESH,ALL FINISH /solu dk,286,all dk,287,all dk,303,all dk,304,all dk,142,all dk,143,all dk,159,all dk,160,all SFA,ALL,1,PRES,-270 ACEL,,9.8 SOLVE SAVE /post1 PLNSOL, U,SUM, 0,1.0  节点位移云图.jpg |
