Abstract

The effect of several parameters to minimize the braking response time has been investigated in this study. The experimental rigs were developed and the results of the experement compared with those of simulation obtained from the net work fluid flow system analysis code (FLOWMASTER). The braking response time and pressure loss were observed at separated braking port and found out that the response time can be reduced by considering the pipe length and environmental thermal conditions. The correlation equation was also presented to predict the pressure loss at various tank pressure.

상용 트럭에서 탑재하고 있는 공압을 이용하는 브레이크 시스템에서 제동시간을 최소화 하기 위해 다양한 인자들에 대한 연구를 진행하였다. 실험 결과와 1차원 유체유동 네트워크 해석코드(FLOWMASTER) 결과와 비교하기 위하여 실험 지그를 제작하였다. 밸브 포트, 파이프 길이, 주변의 열적 환경에 대한 영향에 대해 제동 응답 시간과 압력 감소를 고찰하였다. 또한 탱크 압력에 대한 압력 감소에 대해 상관관계식을 도출하였다.
