踏面制輪子のブレーキダスト高時間分解能測定手法による摩耗挙動の把握

抄録

Understanding the wear behavior of the brake block is necessary to reduce brake block wear and improve brake performance. However, measuring the amount of wear at each moment during braking is currently difficult. Therefore, focusing on the brake dust, a dust measurement method was developed to measure friction behavior with high time resolution and sensitivity. This method captured the differences in the dust emission characteristics of various brake blocks, and linearity was found between the amount of wear and dust except under high load conditions, suggesting the possibility of predicting the wear amount based on the dust measurements.
