离合器
使用离合器模块，可以在不同转速和齿轮比的旋转组件之间传递旋转运动和扭矩。通常，单靠一组齿轮无法实现这种传递。通过构建高保真自定义离合器系统，将离合器与 Gears 库中的多个模块连接起来，可以控制传递动力的时间、方式和大小。使用离合器模块的热变体，可确定产热如何影响传动系统组件的效率和温度。

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.
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.
Washing Machine Fault Analysis
Model a washing machine and introduce a fault in its operation. The machine water supply faults at a specific time and this example models the system response under this scenario. The electric motor switches off and the machine operation is aborted by discharging the partially filled outer drum.
