Flexible Body Modeling with Adams/Solver
The topics in this section explain how to use Adams/Flex with Adams/Solver:
• Steps in Modeling Flexible Bodies with Adams/Solver
• Selecting Modes and Nodes
• Creating Matrix Files
• Writing Flexible Body Statements
It would also be helpful to read the information in the other sections of the Adams/Flex online help even
if you are using Adams/Solver with Adams/Flex. They contain overview material that pertain to
Adams/Solver as well as Adams/View.
Steps in Modeling Flexible Bodies with Adams/Solver
To model a flexible body in Adams/Solver, you do the following as shown in the figure below.
Step 1:
Select
Modes and
Nodes
Step 2:
Create a
Matrix File
Step 3:
Create
Statements
Select the modes that you want included in the dynamic simulation and decide which
nodes will have markers attached.
Translate an created from a finite element analysis (FEA) program to a matrix file. As
you translate the MNF, you specify the selected modes and nodes. You also specify the
units for the matrix file. You use the units that you are using in your (.adm file), not in
your MNF.
Create the following statements in your dataset:
FLEX_BODY statements that describe a flexible body and associate it with matrix
elements.
MARKER statements that create markers at any node locations where you want to attach
modeling elements, measure deformations, and more. You must have included these
nodes in the matrix file.
MATRIX statements that correspond to the matrices in the matrix file.
