Create Belt - 3D Links Nonplanar

Belt Name

Enter the belt name.

Axis of Rotation

Axis of Rotation can be one of the following:

Reference Location

Enter the value for reference location.

Geometry

Total Segments

Optionally enter the total number of segments into which the belt is to be discretized. Use this parameter along with the segment length parameter when the total length of the belt is known and Adams will route a belt of this length through the pulley set and report the resulting tension required to do so.

Segment Length

Enter the length of the individual discrete segments into which the belt model is discretized. Using this parameter in conjunction with "Total Segments" the total length of the belt can be provided as an input (see above). If "Total Segments" is not specified, then Adams will model the belt with the greatest number of segments of this length that still provides some tension (that is, greater than zero belt tension in the design position of the model).

Belt Height

Enter the total height of the belt. It is also known as "Nominal Height".

Belt Width

Enter the width of the belt.

Cordial Distance

Enter the distance from the inner belt surface to the cord inside the belt.

Belt stiffness

Stiffness

If you set Section Connections to Geometry & Material, Adams Machinery displays the following options. Learn how Adams Machinery uses the following options to calculate stiffness parameters.

Segment Area

Enter the cross-sectional area of the segment.

Section Inertia

Enter the area moment of inertia of the segment cross section, about the neutral axis (z-z). It is expressed as unit length to the fourth power. It is sometimes referred to as the second moment of area about the z-axis. The z-axis is along the width of the belt.

For a solid rectangular section:

I = Izz = width * height3/12

where the height of the land-section cross section is (Nominal Height - Tooth Height).

Young’s Modulus

Enter the Young's modulus of the belt material.

Damping Ratio

Enter the damping ratio (damping coefficient).

Shear Modulus

Enter the shear modulus of the belt material.

Shear Correction

Select if the shear correction factor should be included. If selected, a shear area ratio of 1.2 (assuming rectangular cross section) is used for shear deflection both in the z and y directions. See Adams Solver C++ BEAM statement for details on how the elements of the stiffness matrix are calculated for a Timoshenko beam, including shear area ratio.

Longitudinal Stiffness Multiplier

The longitudinal stiffness multiplier will scale the longitudinal stiffness of the belt to mimic the cordial reinforcement of the belt in this direction.

This factor will be multiplied with element K11 and K55 element of the stiffness matrix.

See Adams Solver C++ BEAM statement for more information.

If you select User entered, Adams Machinery displays the following options. Learn how Adams Machinery uses the following options to calculate stiffness parameters.

Translational Stiffness

Enter the value for translational stiffness compliant connection between inward-outward belt.

Rotational Stiffness

Enter the value for rotational stiffness compliant connection between inward-outward belt.

Crossterm Stiffness

Enter the crossterm stiffness.

Translational Damping

Enter the value for translational damping compliant connection between inward-outward belt.

Rotational Damping

Enter the value for rotational damping compliant connection between inward-outward belt.

Crossterm Damping

Enter the crossterm damping.
