Member Function Documentation
| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::AligningMomentArm | ( | ) |
Returns the aligning moment arm.
It is produced about the tire vertical axis using this coefficient and the lateral force acting at the tire/road interface.
Created in NX11.0.0.
License requirements : mechanisms ("MECHANISMS")
| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::CorneringStiffness | ( | ) |
Returns the cornering stiffness constant
Created in NX11.0.0.
License requirements : mechanisms ("MECHANISMS")
| bool NXOpen::Motion::TirePropertyNonInertialBuilder::DistributedContact | ( | ) |
Returns the distributed contact.
If true, the Number of Divisions will be exported with a value required to be higher than 1 , otherwise a value of 0 will be exported to the solver.
Created in NX11.0.0.
License requirements : mechanisms ("MECHANISMS")
| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::FrictionCoefficient | ( | ) |
Returns the friction coefficient between the tire and road.
Should be greater than or equal to zero.
Created in NX11.0.0.
License requirements : mechanisms ("MECHANISMS")
| NXString NXOpen::Motion::TirePropertyNonInertialBuilder::Name | ( | ) |
Returns the unique name of the tire property.
This must be set after this builder is attached to its owner.
Created in NX11.0.0.
License requirements : mechanisms ("MECHANISMS")
| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::NumDivisions | ( | ) |
Returns the number of divisions.
When the distributed contact normal force model is to be used, this variable should be set to the number of vertical "slices" into which the tire is divided. If a simple "point-contact" normal force model is desired, this variable should be set to zero. The distributed contact model should be used when the road profile contains abrupt changes. NumDivisions should be set high enough so that each "slice" is smaller than the smallest road profile feature.

| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::Radius | ( | ) |
Returns the radius.
Created in NX11.0.0.
License requirements : mechanisms ("MECHANISMS")
| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::RollingResistance | ( | ) |
Returns the rolling resistance coefficient of the tire.
It is used to calculate a force as a function of the normal force. This adds to the longitudinal force acting as the tire/road interface. This represents parasitic longitudinal force due to carcass deformation losses, bearing friction, etc., as a fraction of normal force.

| void NXOpen::Motion::TirePropertyNonInertialBuilder::SetDistributedContact | ( | bool | inValue | ) |
Sets the distributed contact.
If true, the Number of Divisions will be exported with a value required to be higher than 1 , otherwise a value of 0 will be exported to the solver.

name name
| void NXOpen::Motion::TirePropertyNonInertialBuilder::SetStaticHold | ( | bool | inValue | ) |
Sets the static hold.
it controls whether or not the tire should generate holding forces during static or quasistatic analysis. When this parameter is true, the tire will generate the following fictitious forces during static analysis, or during the static phase of STATIC/DYNAMIC analysis (see the System Data and Static elements documentation for more details). First, a torque is applied to the chassis to introduce stiffness for vehicle yaw motion. Finally, forces are applied in the fore-aft and lateral chassis directions in order to prevent equilibrium problems. Disabling these forces may cause the static analysis to fail. If the vehicle is on a flat road, then the fictitious forces will yield a physically meaningful static vehicle position. These forces attempt to keep the tire spin angle, chassis lateral/longitudinal postion at their initial values.

| NXOpen::Expression* NXOpen::Motion::TirePropertyNonInertialBuilder::VerticalDamping | ( | ) |
Returns the vertical damping.
It is used in the normal force calculation. A vertical damping coefficient defines the normal force due to vertical deflection velocity.

| NXOpen::Motion::ExpressionFunctionBuilder* NXOpen::Motion::TirePropertyNonInertialBuilder::VerticalStiffness | ( | ) |
Returns the vertical stiffness.
It is specified as an ExpressionFunctionBuilder , depening on the type a constant (expression) or a function will be used. It is the tire stiffness normal to the road profile. Vertical stiffness defines tire normal force as a linear (if a constant is selected) or a non-linear (if a function is selected) function of vertical deflection.
