제동 성능 시험때 차량 Backing Plate 체결 볼트의 강도에 관한 연구

A Study on the Strength of the Mounting Bolt of a Backing Plate During the Braking Performance Test of the Wheeled Vehicle

The strength of the mounting bolt of a backing plate is investigated with field test to provide the basic data in the safety evaluation of the wheeled vehicle. As a result, during the braking performance test at a vehicle speed of 32km/h, the shearing stress of mounting bolt is 20.5kg/mm$^{2}$ because the translatory mass of the vehicle is increased 21.6 per cent to incorporate the rotating-mass effect of wheels and other permanently engaged rotating parts.
