BearingRayleighDampingBeta

The damping matrix for the model C = alphaM + betaK where M and K are the stiffness and mass matrices and alpha and beta are the Rayleigh damping parameters. Typical values for bearings are in the range 1e-6 to 1e-4.

Measurement: TimeShort

Declaration
public Overridable<double> BearingRayleighDampingBeta { get; set; }
Property Value
Type Description
Overridable<System.Double>

BearingStiffnessModel

Concept bearings use 1e9 N/m for the linear stiffness and 1e6 Nm/Rad for the tilt stiffness for any non-linear bearings in the model. The system deflection results will only be accurate if the bearing loads do not change much from the load case. The non-linear bearing model is the most accurate but slow to calculate.

Property Value
Type Description
EnumWithSelectedValue<BearingStiffnessModel>

GearMeshStiffnessModel

Simple stiffness uses the ISO mesh stiffness or specified mesh stiffness for cylindrical gears. Basic LTCA uses a strip model where the potential contact lines are calculated from the macro geometry and then divided into strips. Each strip is given a proportion of the stiffness according to the ISO 6336 Single Stiffness value. Micro geometry is included via a modification of the gaps for each contact point pair.

Property Value
Type Description
EnumWithSelectedValue<GearMeshStiffnessModel>

Declaration
public bool IncludeGearBacklash { get; set; }
Property Value
Type Description
System.Boolean

IncludeMicrogeometry

Select this to include microgeometry in the analysis to obtain a detailed load distribution. This option is not available when any of the gears have a separate micro geometry specified for each of its teeth.

Property Value
Type Description
System.Boolean

IncludeShaftAndHousingFlexibilities

Set to 'Full Flexibilities' to include shaft and housing flexibilities in the analysis for all six degrees of freedom. If set to 'None (Rigid Body)' then shafts and ungrounded housings are treated as torsional only rigid bodies and grounded housings will not be included in the analysis.

StaticLoadCasesToCreate

'Load Cases Over Time' creates the specified number of static load cases between the start and end of the defined period. 'Peak Loads For Gears' creates load cases for each gear. These represent the worst possible scenario where one tooth always sees the peak load. For a gear with multiple meshes it is assumed that the same tooth sees the peak load on every mesh, which is conservative.
