Clutch Applications

Example models illustrating clutch applications

Clutches allow for safe engagement and disengagement of power transmission members. These examples demonstrate various clutch implementations.

Featured Examples

Automotive Clutch

Model, parameterize, and test an automotive clutch. Running the model plots the engine and transmission speed during a declutching scenario.

Clutches for Accelerating and Braking

The use of clutches to accelerate and decelerate a pair of shafts connected by a gearbox. The gear connects the output and intermediate shafts. The inertia for both of these shafts is included in the Inertia Output Shaft component. This pair of shafts is connected via one clutch to a drive shaft which is driven by a torque. These shafts are also connected via a second clutch to a stationary point.

Custom Clutch

Two inertias coupled by a simple gear controlled by a clutch. Initially, the clutch pressure is zero, and the inertias have zero velocity. A constant torque is applied to Inertia 1. Once the clutch pressure starts increasing from zero at 2 seconds, Inertia 2 starts spinning, then locks with Inertia 1. From 6 to 7 seconds, the clutch pressure is ramped down to zero, and Inertia 2 starts to spin freely once the clutch unlocks. Because there is no frictional loss, it keeps spinning.

Open Model

Dog Clutch with Dynamic Modal Model

The engage and disengage behavior of a dog clutch using the dynamic modal model for torque transmission. The block parameterization uses mode charts to control the clutch engagement. The clutch fails to engage when the speed difference between the ring and hub is too great.

Open Model

Hydraulically-Actuated Driveline Clutch

An engine driving an inertial load via a hydraulically-controlled clutch. It shows how Simscape™ Driveline™ can be used in conjunction with Foundation Library isothermal liquid blocks to model hydraulically-actuated drivelines.

Open Model

Hydraulic Clutch System

Model, parameterize, and test a hydraulic clutch system. The model is used to generate the plot of the engine and the transmission system speeds during a declutching and clutch re-engaging scenario.
