Week -2

Aim :

To make a simulink modelof a doorbell.

Theory:

In the electric bell when the switch is closed the electromagnet recives the electri power from thye batterywhich pulls the metal hammer asnd produces the sound.

Simulink model of door bell :

Blocks used:

Pluse Generator: for generating a time interval to control.

Simulink-PS convertor: To convert simulink sysytem to physical system.

Battery: For power supply.

Switch: The block represents a switch controlled by an external physical signal. If the external physical signal PS is greater than the threshold, then the switch is closed, otherwise the switch is open.

PS-Simulink converter: To convert physical system to simulink system.

Elecrical Referance: It contain at least one electrical reference port (electrical ground).

Mechanical Translational reference: To ground the mechinical blocks.

Solver Configuration: It defines solver setting to use for simulation.

Ideal Translational motion sensor: Converts an variable measured between two mechanical tranlational nodes into a control signal proportional to velocity and position.

Scope: For the velocity and position values.

Output:

Velocity plot:
