| Summary: | 碩士 === 大葉大學 === 機械工程學系碩士班 === 92 === In this research report we have an overall study on current regulations of the motor vehicle horn volume and try to understand the reason why we have those regulations in our country. For purposes of ensuring the quality of measurement of motor vehicle horn volume and more reliable testing results, we furthermore design an alternative measurement procedure of motor vehicle horn volume to improve the testing results which may be flawed by improper personal manipulation during the process of measurement . In addition, we find that the value of the measured volume is slightly larger and results of the measurement are more impartial when the honk timing is controlled by a timing relay device instead of controlled by human operation.
There are three parts in this report. First, we provide a collective analysis and comparison of domestic and international regulations of motor vehicle horn volume. Second, we design and construct a timing relay device and conduct the preparation of relevant test vehicles. Third, we make a statistical analysis of the measured values of the motor vehicle horn volume, of which the honk timing is both controlled by a timing relay device and by human operation.
