Properties

BeltLossConstant

A constant dependent on the belt and pulley design. The efficiency reduces in a linear function as the safety factor is increased, the slope = -'Belt loss constant' X 'cos(sheave angle)' / 'coefficient of friction'.

Declaration
public double BeltLossConstant { get; set; }
Property Value
Type Description
System.Double

CoefficientOfStaticFrictionWithLubrication

The coefficient of static friction with lubrication between elements and sheaves

Declaration
public double CoefficientOfStaticFrictionWithLubrication { get; set; }
Property Value
Type Description
System.Double

ContactStiffnessForUnitLength

Measurement: StiffnessPerUnitFaceWidth

Declaration
public double ContactStiffnessForUnitLength { get; set; }
Property Value
Type Description
System.Double

CrossSectionalAreaOfThePumpOutlet

Area of outflow

Measurement: SmallArea

Declaration
public double CrossSectionalAreaOfThePumpOutlet { get; set; }
Property Value
Type Description
System.Double

PulleySheaveAngle

Pulley sheave angle is half the angle between two pulley sheaves

Measurement: Angle

Declaration
public double PulleySheaveAngle { get; set; }
Property Value
Type Description
System.Double

PumpDisplacementPerRevolution

The amount of fluid moved by the pump per revolution

Measurement: Volume

Declaration
public double PumpDisplacementPerRevolution { get; set; }
Property Value
Type Description
System.Double

PumpPressureLossConstant

A dimensionless constant dependent on the pump design. The pump power loss depends on the pressure and pump rotation speed, the power loss due to pressure is equal to the 'pressure loss constant' X 'cross section area of the pump outlet' X 'pressure' X 'speed'.

Declaration
public double PumpPressureLossConstant { get; set; }
Property Value
Type Description
System.Double

PumpSpeedFactor

Pump Speed Factor dependent on the CVT design, it is the ratio of the pump speed over engine speed.

Declaration
public double PumpSpeedFactor { get; set; }
Property Value
Type Description
System.Double

PumpSpeedLossConstant

A dimensionless constant dependent on the pump design. The pump power loss depends on the pressure and pump rotation speed, the power loss due to speed is equal to the 'speed loss constant' X 'cross section area of the pump outlet' X 'viscosity' X 'speed squared'.

Declaration
public double PumpSpeedLossConstant { get; set; }
Property Value
Type Description
System.Double

TangentialStiffness

Measurement: StiffnessPerUnitFaceWidth

Declaration
public double TangentialStiffness { get; set; }
Property Value
Type Description
System.Double

UseImprovedModel

This is the flag for new CVT functionality under development. For the first phase of development we are aiming to include sheave moments due to the clamping force.

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

Implements
