| Summary: | 碩士 === 吳鳳科技大學 === 光機電暨材料研究所 === 102 === If vehicle braking system can function and work securely is the most basic issue for driving safe. Due to rapid continous growth of the number of vehicles in Taiwan, general administration institute of roads and traffic partially opens some vehicle inspection supervision businesses to domestic companies to enhance the public service. For example, cars annual inspection routines could be executed by the entrusted units, and entrust some automobile factories for implementation of inspection business for licensing new cars. This study is to establish the sound checking system for the brake test systems of road supervision authorities. And explore the different loading rates and the effect of hysteresis of loading how to affect the identification accuracy of the brake test systems.
This study was to evaluate the accuracy of the two existing brake testers according to the analysis of the data collected from inspection units. In this study, we took into account the brake test values from two brakes of different design concepts and measurement mechanisms, the opinion from professionals actually undertaking inspection, and the proposals from experts and scholars. Afterwards, we implemented the study of brake force differences meeting the feasibility of data collection. Experimental results and quality assurance statistics show that b-type brake force test device has better accuracy. However, prone to shock effect in case of no load protection facilities, it is not suitable the brake tester for large vehicles. This research could provide important reference for the existing inspection processes of the brake test, and better safeguard to the safety of owners and passers-bys.
