大家好 我建立了风管和支架的模型 我想分析支架的受力 下一步我应该怎么做

[Nanda]

Hello User,

You should assign a boundary condition to the supports (*BOUNDARY_SPC). If it is fixed, then constrain all DOFs. In LS-DYNA, to extract reaction forces at a support defined by *BOUNDARY_SPC, the reaction forces are typically output using the *DATABASE_SPCFORC command, which creates an SPCFORC file containing the reaction forces at the nodes where the boundary conditions are applied.

Hope this helps.

Regards,

Nanda.

谢谢你 我应该使用*BOUNDARY_SPC下面的哪个卡片

[Nanda]

Hello User,

You can use *BOUNDARY_SPC_NODE_SET, create a node set for all the supports you have. Under card1, assign the created NSID, and constrain your DOFs accordingly. DOFX, DOFY, and DOFZ are translational DOFs. DOFRX, DOFRY, and DOFRZ are rotational DOFs.

Regards,

Nanda.
