Summary:

With the growing trend of electric vehicles (EVs) incorporating regenerative braking systems, many compact SUVs, including hybrids and EVs, still utilize drum brakes on the rear wheels to strike a balance between cost, performance, and durability. Drum brake squeal remains a complex and persistent challenge in the field of vehicle noise, vibration, and harshness (NVH). This issue stems from dynamic instability caused by timedependent friction forces. Traditional linear modal analysis has been used to study the mechanisms behind drum brake squeal, focusing on harmonic vibrations in largescale models. However, these methods often fail to accurately correlate with real world behavior due to the presence of extra, non-physical modes. To address this, timedomain analysis approaches have been explored, incorporating detailed friction models and contact mechanics. These methods consider different root causes for high and lowfrequency squeal and have shown promising results in accurately predicting brake squeal behavior when validated against experimental data
