Design and Implementation of a Kinematic Measurement System to Torsional Deformation of a Shaft
摘要
Abstract
This paper designed and achieved a kind of real time kinematic measurement system to angel of torsion based on phase difference method with the core design of FPGA.This system＇s color code transducer used to measure speed and torque was composed of reflective laser probe and color code made on the revolving shaft.The outputs were in the form of impulse and phase difference while professional phase demodulation,period and pulse width measurement module focus on FPGA.Stimulating,field proving and actual testing show that the system measuring accuracy is superior to 0.5% full span within the measuring range of 0 to 2000N·m.As a result,it can effectively solve kinematic measurement to angel of torsion,torque and power of high rolling shafts under tough circumstances.关键词
