Abaqus plane strain
Abaqus plane strain
(OP)
Hi all!!!
I try to model two gear using plane strain element in Abaqus.
In particular I have made one gear using element CPE3 and CPE4, plane strain element in Abaqus, and the second gear (the driving gear) that have higher stifness than other gear with rigid element R3D3 and R4D4.
After I have made contact between two gear.
After that I launch the solution the .dat file send me the following error:
***ERROR: THE SLAVE AND MASTER PAIR (DEF_SLAVE_GEAR,
RIG_MAST_GEAR) IS INCOMPATIBLE IN DIMENSION. PAIRING A 2D OR AN AXISYMMETRIC SURFACE WITH A 3D SURFACE IS NOT ALLOWED.
The error depend to incopatibility between the element in use.
Someone can help me to solve this kind of problem?
Is there somebody that have met this kind of problem and send me .inp file o abaqus to study it?
I'm waiting an answer as soon as possible,
Bye and thx

RE: Abaqus plane strain
3-D rigid elements
R3D3 3-node, triangular facet
R3D4 4-node, bilinear quadrilateral
RB3D2(S) 2-node, rigid beam
I am not sure on the technique used, but perhaps try model the perimiter/boundary of your stiff gear with R2D2 elements. Otherwise use deformable elements and input a very high stiffness?
There are methods to use multiple model spaces in the same analysis - such as axisymmetric and plane stress - see example problem 1.1.1 in your documentation. CAE often throws it's toys when you do this, generally you need to manually edit the input file.
You may need to employ modified contact geometric properties to describe how deep the contact surface is.
