For the option: | Do the following: |
|---|---|
Gear Force Name | Enter the name of the 3D gear force element. |
Gear 1 | Enter the name for Gear 1. |
Gear 2 | Enter the name for Gear 2. |
Property File | You can reference to available property file to specify input parameters for gear and force. |
Contact Stiffness | Enter a value for the stiffness coefficient of the gear-to-gear contact. Note: The stiffness coefficient should always be the translational stiffness, that is, with units Force/Length. To get a full description of all contact parameters please refer to the online help for the IMPACT function. |
Contact Exponent | Enter a value for the contact exponent of the gear-to-gear contact. |
Contact Damping | The contact damping is always expressed be the translational damping, that is, with units Force-Time/Length, regardless if the backlash is measured as an angle or a length. The damping will be converted to appropriate units in the machinery solver code. |
Contact Penetration | The contact penetration parameter defines the depth at which full damping is reached for the contact. |
Static Friction Coefficient | Specifies the coefficient of friction at which the transition between static friction and dynamic friction starts. |
Static Friction Velocity | Specifies the relative sliding velocity at which the transition between static friction and dynamic friction starts. |
Dynamic Friction Coeff. | Specifies the coefficient of friction at a contact point when the slip velocity is larger than the Dynamic Friction Velocity. |
Dynamic Friction Velocity | Specifies the relative sliding velocity at which the transition between static friction and dynamic friction ends. At sliding velocities higher than the Dynamic Friction Velocity, the Dynamic Friction Coefficient will be used. |
