For the option: | Do the following: |
|---|---|
Input Shaft to Gearbox | Specify the gearbox input shaft part. Adams Driveline creates entities such as attachments between the input shaft and the hub of the friction disk. This part must already exist. |
Flywheel Part | Specify the flywheel part. You can select either a general rigid part or a mount part. Very often the flywheel is modeled in the engine template, while the clutch is modeled in the gearbox template. |
Reference Construction Frame | Specify the construction frame used to locate all parts and attachments. As shown in the figure Clutch Assembly, this construction frame must have the z-axis pointing toward the end of the input shaft and has to be located at the beginning of the gearbox input shaft. |
Max Deattaching Force | Enter a real number that specifies the maximum force that can be exerted when releasing the clutch. Adams Driveline uses this value to create an actuator force whose expression is: Force = - Max Detaching Force * (1-VARVAL(Clutch Demand)) Clutch Demand |
Clutch Demand Adams Id (optional) | You can: ■Leave it blank - Adams Driveline automatically creates a Solver variable single input communicator named Torque_demand. ■Select this communicator from the Database Navigator. This communicator gets the clutch signal (0/1) from the test rig. |
Pressure Spring Name | Enter the name of the spring element between the flywheel and the pressure plate. See the figure Clutch Assembly. |
Preload | Specify the preload of the spring element connecting the flywheel to the pressure plate. |
Property File | Enter the property file for the force versus displacement characteristic of the flywheel pressure-plate spring component. |
Pressure Plate Name | Enter the string for the pressure plate part. Adams Driveline creates this part and positions it according to the number of friction disks you want to create. See the figure Clutch Assembly. |
Pressure Plate Name: Mass | Specify the mass characteristics for the pressure plate part. |
Pressure Plate Name: Inertia | Izz is the inertia around the longitudinal axis of the input shaft. Ixx and Iyy are not important because the parts are only rotating around the z-axis. |
Friction Disk Name | Enter the string for the friction disk part. Adams Driveline creates this part and positions it according to the number of friction disks you want to create. See the figure Clutch Assembly. |
Friction Disk Name: Number | Specify the number of friction disks you want to create in the clutch assembly. |
Friction Disk Name: Radius | Enter a real number that specifies the effective radius of the friction disk. Adams Driveline uses this number to generate a simple graphic for this part and to evaluate friction forces between friction disks and other parts of the clutch assembly. |
Torsion Spring: Stiffness | Specify the stiffness. (clear) |
Torsion Spring: Damping | Specify the damping. (clear) |
Torsion Spring: Mass | Specify the mass characteristics for each friction disk part. |
Torsion Spring: Inertia | Izz is the inertia around the longitudinal axis of the input shaft. Ixx and Iyy are not important because the parts are only rotating around the z-axis. |
If you selected a number greater than 1 in the Number text box, Adams Driveline displays the following three options: | |
Intermediate Plate Name | Specify the intermediate plate part. Adams Driveline creates this part and positions it according to the number of friction disks you want to create. See the figure Clutch Assembly. |
Intermediate Plate Name: Mass | Specify the mass characteristics for the intermediate plate part. |
Intermediate Plate Name: Inertia | Izz is the inertia around the longitudinal axis of the input shaft. |
Clutch Property File | Specify the property file for clutch contact force characteristics. For example, <db_name>/clutch_forces.cdb/*.clu. |
Clearance | Enter a real number that specifies the displacement available before contact forces start to arise. |
Friction Radius | Enter a real number that specifies the effective radius of all friction surfaces. Adams Driveline uses this number to evaluate friction forces between friction disks and other parts of the clutch assembly. |
Mu Static, Mu Dynamic, Static Vel, and Dynamic Vel | Enter real numbers that specify the friction characteristics of the clutch assembly. For a rotational velocity equal to Static Vel, the friction coefficient is equal to Mu Static. As soon as the rotational velocity is equal to Dynamic Vel, Adams Driveline sets the friction coefficient to Mu Dynamic. A small amount of slip is always needed to have friction forces. |
