FEM Analysis of Caliper Housing Cut Inside Upper Face for Unbalance Wear Prevention of Disk Brake Pad

디스크 브레이크의 편마모 방지를 위한 finger 안쪽면 윗 부분이 가공된 캘리퍼 하우징의 유한 요소 해석

The purpose if this research was to improve the pressure distribution on the disk brake pad Not uniform pressure distribution on the disk brake pad generate the unbalance wear of it and the unbalance wear of disk brake pad generate vibration, noise, heat and reduce the braking capacity. For improve the pressure distribution on the pad in this research, upper face of caliper housing finger was cut. Two kinds of caliper which uncut and cut of finger face were compared the stress distribution by FEM analysis and real experiment. Also natural frequency and deforming displacement ware calculated. It was understood that pressure distribution could Improve by cut inside upper face of caliper housing finger.
