Hi Bertug,
To simulate the engagement of two helical gears in Simulink or Simscape, where one gear has random RPM and the other is controlled, the following components are required:.
- Uncontrollable Gear: The ‘Ideal Angular Velocity Source’ block can be used here to simulate the random RPM of the uncontrollable gear.
- Controllable Gear: The ‘Ideal Torque Source’ allows to control the torque applied to the gear, which in turn controls its speed.
- Differential Element: ‘Differential’ block is used to simulate the engagement of the two gears.
- PID Controller: ‘PID Controller’ block can be used to control the torque applied by the torque source.
- Sensors and Scopes: ‘Ideal Rotational Block sensor’ measures the RPM of both gears. ‘Scope’ blocks can be connected to visualize the RPM and control signals.
The ‘Ideal Angular Velocity source’ can be connected to ‘Random Number’ block to generate a random RPM input.
The 'PID controller' and 'Differential' block can be configured as follows :
- Output of the RPM sensor on the uncontrollable gear should be connected to the input of the PID controller.
- Output of the PID controller should be connected to the ‘Torque Source’ to control the torque applied on the controllable gear.
- Finally, the outputs of both uncontrollable and controllable gears must be connected with ‘Differential’ block and a manual switch can be used to engage the differential once the RPMs are synchronized and steady.
I hope this helps.
