角加速度测
Angular acceleration measurement
以上为机器翻译结果,长、整句建议使用 人工翻译 。
介绍了一种发动机无外载功率检测系统的软、硬件设计,利用测频法测量出某一时刻的瞬时速度,并利用最小二乘法求出角加速度。
By the method of frequency measurement, instant rotational speed is measured in the test system, angular acceleration is calculated by using the feature of the MCU with the least square method.
