Development of a Model for Predicting Brake Friction Lining Thickness and Brake Temperature

Abstract

Road traffic injuries and deaths are a growing public health concern worldwide, majorly in developing countries. Brake failure constitutes to be one of the primary reasons for accidents. The majority of brake failures are caused due to overheating of the brakes, while wear of lining is another big share-holder. Early detection of such causes can prevent these accidents. This study puts forth a model that can be used for onboard monitoring of drum/disc temperature & lining/pad thickness by taking velocity & road inclination in real-time as inputs. Many quantities are interdependent and vary with respect to time/temperature. Therefore, an incremental approach is used. The model is implemented in the Simulink software. Many standard profiles are also fed to compare results for different terrains and driving conditions. The drivers can also be classified based on their driving behavior. The thermal model can give us an early warning about the brake overheating. This model can be used to study the energy distribution while braking. Researchers and designers can also use this model to study & optimize the brake system.

Bir Mikrokanaldaki Kayma Akışında Basınç Kaybı Analizi

“…Örneğin, bir kanalın hidrolik çapındaki azalma, hacminde söz konusu alanındakinden daha büyük bir azalma meydana getirmektedir, yani mikro-akışkanlı sistemlerde alanhacim oranı çok yüksek olma eğilimindedir. Bu sayede, mikroakışların davranışı, normal boyutlu borulardaki akışlardan tamamen farklı olabilir [2][3][4][5][6][7][8].…”

“…HAD ile gerçeğe çok yakın analizler yapıldığı için, deney ve prototip testlerinin maliyetleri de büyük oranda azalmıştır. Bunun doğal sonucu olarak da ürünlerin fiyatı düşmüştür [8][9][10][11][12][13][14][15].…”
