The advantages and disadvantages of the in cab speedometers for ICE and TGV high speed trains were analyzed, using SSSI and EID man machine interface design theories and the theoretical assumptions were further confirmed through the experiments. 应用SSSI和EID两个人机界面设计理论分析了德法两国高速列车司机室中速度表的优缺点,并通过实验进一步验证了理论假设。
This paper gives examples of the construction, working principle and trouble shooting of speedometers commonly used on domestic motor vehicles. 介绍了国产汽车常用车速里程表的结构、工作原理与故障检修方法。
Compared with the traditional speedometers which are difficult to achieve accurate velocity measurements for high-speed ships, microwave speed radar is such a non-contact measurement system which is able to measure the relative velocity of the sea for any high-speed ships, in any sailing posture. 与难以实现对高速新型舰艇进行准确速度测量的传统测速仪相比,微波测速雷达这样一种无接触式的测量系统能保证任何高速舰船,在任意航行姿态下,测量其与水面的相对运动速度。
