초록
In this study, we investigated the noise characteristics using the friction curve of an ABS material where surface changes occurred owing to continuous friction using a friction test apparatus. To artificially generate instability, the acceleration and the friction coefficient were measured after 90000cycles rubbing at a normal force of 40N and a velocity of 80mm/s. The change in the slope according to the coefficient of friction and the slip speed is considered to be an important factor of friction noise and it can be inferred that the slope of the sound is caused by the accelerated durable friction noise. It can be inferred that the moment the slope becomes negative is the endurance life of ABS.
