Hi Quan,
I understand that you are trying to develop a transmission model with “Torque Converter” (TC) and “Variable Ratio Transmission” (VRT) blocks. Please follow the below steps, to introduce vibrations in the system,
- Understand the vibration that must be added and collect its frequency, phase shift and amplitude. Model the vibrations, using a “sine wave” block.
- “r” port of the “VRT” block represents input-to-output shaft velocity ratio. The vibrations can be introduced here. Add the sine wave block to the incoming signal of “r” port using an “add” block.
- The output of the “add” block must be sent to a “Simulink PS converter” block and then connected to the “r” port.
Using the following method, vibrations can be introduced in the “TC” + “VRT” system. For more information on the “VRT” block and for an example of “Variable ratio gear”, Please refer to the following documentation link:
I hope this helps!
Thank you,
Abhimenyu.
