Modeling Gears, Clutches, and Dynamic Elements

SimDriveline includes block libraries for the components that define motion and torque relationships between connected shafts.

Libraries of Common Gear Configurations

SimDriveline lets you develop both simple and complex gear systems. Predefined blocks are provided for the basic gear configurations. You characterize these blocks by assigning the appropriate gear ratio.

You can combine these simple configurations to create more complex gear systems, such as those found in transmissions. SimDriveline also provides models for commonly used complex gear systems, such as Ravigneaux gear sets and differentials.

Standard schematics label each gear block to show which arrangement of gears and carriers it represents.

Clutches and Other Dynamic Elements

SimDriveline includes a library of dynamic elements that, together with the gear sets, provide a complete set of driveshaft connectors. For example, the Controllable Friction Clutch models the action of a clutch as it engages and then locks shafts moving at different rotational speeds. The Controllable Friction Clutch employs a kinetic friction model for the transition and a static friction model for the locked condition.

SimDriveline also includes the following dynamic elements:

• Torque Converter—lets you model fluid-bearing connections
• Hard Stop—lets you include backlash in your driveline and account for the resultant power loss
• Torsional Spring-Damper—lets you model a damped torsional spring with backlash
