| 摘要： | PD-LTV Engineering requested assistance with research that would enable the writing of an ATPD documenting a procedure for evaluating the brake system performance in a realistic mountain driving environment. A literature search was undertaken to identify test procedures and test sites that were utilized by automobile manufacturers, NATC, ATC, and the University of Michigan Transportation Research Institute (UMTRI). Potential mountain road test venues documented by R&R Publishing were examined for severity by estimating the brake temperatures resulting from the length and grade of the road, and the speed limit using a fundamental analysis documented by UMTRI. The severity of these roads was compared to the estimated temperature from executing the MRAP FoV CPD requirement to descend a 10 mile long 6% grade at 45 mi/h and to existing known Government and automotive industry test standards. Several candidate mountain roads for evaluation were recommended based upon estimated brake temperature and safety considerations. Guidelines for the evaluation of the test venues were also proposed. In addition, several automotive standards and Government test procedures were simulated and their brake temperature severity compared. |
