- Brake moan noise is low-frequency noise occurring at low speed. Multiple factors like stick-slip, mode coupling and atmospheric conditions can be the cause. For the MotionSolve model, the input of the friction curve is required.
- Bajaj Auto uses three classes of Brake pads: a.Organic b. Sintered c. High COF Organic. The pads are procured from different vendors, thus the composition of the pad is different. Each pad has a different friction curve which affects the brake moan propensity due to stick slip.
- Experiments were conducted on the Brake Test Bench to understand the variation of the COF with temperature, pressure and disc velocity. The experiments were conducted for many brake cycles. Multi-class time series data is generated through the experiments.
- Pandas and NumPy Library is used for Data import, DataFrame storage, Aggregation and Data manipulation. Visualization is done with Matplotlib.
- KNN is used to remove the outliers from the dataset. (PyOD library)
- Regression of the data is done with the sci-kit learn library and some in-house codes. The model is trained on 60% data, tested on 20% data and validated with the remaining dataset for accuracy.
- Dataset and the trained model is stored in pickle data format for easy access.
