1、受均布载荷简支梁剪力弯矩计算过程受均布载荷简支梁剪力、弯矩计算过程一、进入ANSYS二、定义路径及文件名三、定义单元类型用鼠标按顺序操作:(prep/element type/add)四、定义梁截面(矩形截面:宽1m, 高2m)Prep/section/common section五、定义材料属性(弹性模量:2E11Pa;泊松比:0.3)Prep/material models/favorites/linear static/linear isotropic六、建模1、生成点keypoint(0,0,0), (10,0,0), (0,3,0)Prep/modeling/create/keypo
2、int/in active CS生成点1后,生成点2,用键盘修改2、3处数值即可同样生成3点2、由1、2点生成直线Prep/modeling/create/lines/lines/straight line出现下面对话框时用鼠标点击1、2点或用键盘输入后回车均可。七、划分单元1、定义线的属性(1)定义关键点Prep/meshing/mesh attributes/all lines (2)定义单元数(单元数:50)Prep/meshing/meshtool2、分网 Prep/meshing/meshtool/mesh出现对话框用鼠标单击线或用键盘输入1后回车均可。八、加载1、位移约束Solut
3、ion/define loads/apply/structural/displacement/on node出现对话框后用鼠标单击节点1或用键盘输入将1点X、Y、Z方向位移及X、Y方向转角约束为0。用同样方法约束2点Y方向位移。2、施加均布载荷(1)选择节点(选择Y=0节点)Select/entities/node/by location(2)加载(线载荷1*101/10=10.1N/mm)Solution/define loads/apply/structural/force/on nodes (3)求解 选择全部模型Select/everything Solution/solve/curr
4、ent LS九、进入后处理查看弯矩结果1、定义单元表General postproc/element table/add/by sequence num/smisc,2用同样的方法定义SMISC,23、画弯矩General postproc/plot results/contour plot/line elem res命令流:/PREP7 ET,1,BEAM189SECTYPE, 1, BEAM, RECT, , 0 SECOFFSET, CENT SECDATA,1,2,0,0,0,0,0,0,0,0 EX,1,2 PRXY,1,0.3 K, , K, ,10, LSTR, 1, 2 K, ,3,LATT,1, ,1, , 3, ,1 LESIZE,1, , ,50, , , , ,1 LMESH, 1 FINISH /SOLD,1, , , , , ,UY,UZ,ROTX,ROTY, , D,2, , , , , ,UY, , , , ,NSEL,S,LOC,Y,0F,all,FY,1 alls,all /STATUS,SOLUSOLVE /POST1 ETABLE, ,SMISC, 2 ETABLE, ,SMISC,15 PLLS,SMIS2,SMIS15,1,0
