一、瞬时角速度和角加速度测量电动机、柴油机等动力设备的研究、制造和使用过程中,需要测量它们的瞬时特性。近十几年来,各国提出不少数字测量法。但是各种数字方法在1972年以前只能测量10毫秒和100毫秒间的平均角速度,测量精度也只达到1%。哪一种方法都不能测量角加速度,它们完全不能适应目前实 First, the instantaneous angular velocity and angular acceleration measurement Motor, diesel engine and other power equipment research, manufacture and use, you need to measure their instantaneous characteristics. In the past decade or so, many countries have proposed many digital surveying methods. But all kinds of digital methods can only measure the average angular velocity between 10 milliseconds and 100 milliseconds before 1972, and the measurement accuracy only reaches 1%. Which method can not measure angular acceleration, they can not adapt to the current reality
