摘要
旋转机械的角加速度是反映其运行状态的重要参数,因此设计了一种基于霍尔效应的新型角加速度测量系统。系统包括霍尔式传感器和数字信号处理器,通过安装在旋转机械转轴上的磁钢和霍尔传感器获取转速信号,对转速信号进行滤波和整形处理,再对转速信号进行数字微分,最终得到旋转机械的角加速度值。构建了旋转角加速度测量系统的框架,对部分模块和系统进了仿真,验证了设计的正确性。最后对步进电动机进行了角加速度测试实验,结果表明该角加速度测量系统具有较强的实用性。
A new angular acceleration measurement system based on FPGA is presented in order to reflect machine＇s state. Firstly, the speed signal is obtained through the hall sensor and the magnets that installed on the shaft of rotary system, then the speed signal is processed by filtering and shaping, and digital differential by FPGA, the angular acceleration of rotary system is received finally. The theoretical formula of angular acceleration is deduced, and the angular acceleration measurement principle is simulated by software. Last, the angular acceleration of actual rotating equipment is tested, and the result of experiments show that the angular acceleration measurement device of this paper with strong practicability.
