For the option | Do the following |
|---|---|
Belt Segment | |
Defining Mass Properties The belt consists of one land part and one tooth part for every tooth. You enter the mass, inertia, and center of gravity for the land part and the tooth part separately. For both land and tooth sections, the part is located in the center of the cord. | |
Land/Tooth section Mass | Enter the mass of the belt segment. |
Center of Mass location with respect to part | Enter the belt segment's center of mass location relative to the belt segment coordinate system shown here. |
Inertia | |
Ixx | Enter inertia with respect to Z axis of the belt segment coordinate system shown above. |
Iyy | Enter inertia with respect to Y axis of the belt segment coordinate system shown above. |
Izz | Enter inertia with respect to Z axis of the belt segment coordinate system shown above. |
Contact Parameters | |
Contact Parameters | Choose between using standard contact formulation to define the belt and pulley interaction by specifying separate contact parameters for the land section and the tooth and using a user defined contact formulation using user SUBroutine. ■Create ■User Subroutine |
Land/Tooth Contact Parameters You can measure the belt contact forces by creating requests; see Create/Modify Belt Segment Request(s) or Create/Modify Belt Span Request(s). | |
Contact Force Preview | Select to display the Data Editor/Viewer and plot the force characteristics based on the specified stiffness, scale factor, and force exponent. Adams Machinery plots only the stiffness force, as shown in the impact figures. |
Stiffness | Enter contact stiffness coefficient of the contact force formulation. These parameters define the typical Adams contact model described by the IMPACT function. |
Scale Factor | Specify the scale factor of the contact force formulation. The scale factor is in length units. These parameters define the typical Adams contact model described by the IMPACT function. |
Exponent | Specify the exponent of the contact force formulation. The exponent is typically larger than 1. These parameters define the typical Adams contact model described by the IMPACT function. |
Damping | Specify the damping coefficient of the contact force formulation. The damping is in force units * time units/length units. These parameters define the typical Adams contact model described by the IMPACT function. |
Penetration Depth | Specify the penetration depth of the contact force formulation. The penetration depth is in length units. These parameters define the typical Adams contact model described by the IMPACT function. |
Defining User Contact Formulation The belt and pulley interaction is handled by a user-written subroutine. For the details regarding the use of the User Subroutine option see section Using user subroutines for contact and friction in Adams Machinery belt. | |
Contact Subroutine Parameters | Contains the parameters that go directly into the contact subroutine. |
Friction Parameters | |
Friction | Choose between using standard friction formulation and using a Contact Friction Force user SUBroutine (CFFSUB). ■Create ■User Subroutine |
Friction Coefficients | |
Static Friction Coeff | Enter the static friction coefficient of the contact, which is the maximum value of the friction. |
Dyn. Friction Coeff | Enter the dynamic friction coefficient of the contact. |
Transition Velocity | Enter the static friction transition velocity. Adams Machinery calculates the dynamic friction transition velocity as 1.2 times this value. |
Defining User - Written Friction Subroutine The belt and pulley interaction is handled by a user-written subroutine. For the details regarding the use of the User Subroutine option see section Using user subroutines for contact and friction in Adams Machinery belt. | |
Friction Formulation | Select to use user subroutine (CNFSUB). |
Friction Subroutine Parameters | Contains the parameters that go directly into the friction subroutine. |
