TwoPointSpringDashpot object

The TwoPointSpringDashpot object defines springs and/or dashpots between two points on a part or an assembly.

The TwoPointSpringDashpot object is derived from the SpringDashpot object.

TwoPointSpringDashpot(...)

This method creates a TwoPointSpringDashpot object.

Path

mdb.models[name].parts[name].engineeringFeatures.TwoPointSpringDashpot
mdb.models[name].rootAssembly.engineeringFeatures\
.TwoPointSpringDashpot

Required arguments

name

A String specifying the repository key.

regionPairs

A sequence of pairs of Region objects specifying the points between which the springs and/or dashpots are applied.

axis

A SymbolicConstant specifying whether the axis of the springs and/or dashpots follows the rotation of the nodes or is in a specified direction. Possible values are NODAL_LINE and FIXED_DOF.

Optional arguments

dof1

An Int specifying the degree of freedom with which the springs and/or dashpots are associated at their first points. The dof1 argument applies only when axis=FIXED_DOFS. The default value is 0.

dof2

An Int specifying the degree of freedom with which the springs and/or dashpots are associated at their second points. The dof2 argument applies only when axis=FIXED_DOFS. The default value is 0.

orientation

None or a DatumCsys object specifying the local directions for the spring and/or dashpot. If orientation=None, the spring and/or dashpot data are defined in the global coordinate system. The default value is None.

The orientation argument applies only when axis=FIXED_DOFS.

springBehavior

A Boolean specifying whether to apply spring behavior to the selected point pairs. The default value is OFF.

At least one of the arguments springBehavior=ON or dashpotBehavior=ON must be specified.

dashpotBehavior

A Boolean specifying whether to apply dashpot behavior to the selected point pairs. The default value is OFF.

At least one of the arguments springBehavior=ON or dashpotBehavior=ON must be specified.

springStiffness

A Float specifying the force per relative displacement for the springs. The default value is 0.0.

dashpotCoefficient

A Float specifying the force per relative velocity for the dashpots. The default value is 0.0.

Return value

A TwoPointSpringDashpot object.

Exceptions

None.

setValues(...)

This method modifies the TwoPointSpringDashpot object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the TwoPointSpringDashpot method, except for the name argument.

Return value

None.

Exceptions

None.

Members

The TwoPointSpringDashpot object has members with the same names and descriptions as the arguments to the TwoPointSpringDashpot method.

In addition, the TwoPointSpringDashpot object has the following member:

suppressed

A Boolean specifying whether the spring/dashpot is suppressed or not. The default value is OFF.
