摘要: 针对目前静态扭矩校准无法完全满足使用需求的问题,设计了一种制动式正弦法动态扭矩传感器校准装置,利用伺服电机、磁粉制动器等装置组成制动扭矩激励系统,用标准惯量盘作为负载,用圆光栅测量惯量盘扭摆的角加速度,将动态扭矩溯源至惯量和角加速度参数。通过建模和数值分析,阐述了校准装置的工作原理,利用研制的校准装置样机进行激励试验,试验结果证明了设计思路的可行性。

Abstract: In order to solve the problem that static torque calibration cannot fully meet the use requirements at present,a sinusoidal dynamic torque sensor calibration device based on braking excitation is designed.In the system of the calibration device,the braking torque excitation part is composed of servo motor,magnetic particle brake and some connecting parts,the inertia disk is used as the load,and the angular acceleration of the inertia disk is measured with a circular grating.Through this calibration device,the dynamic torque is traced to the inertia and angular acceleration parameters.Through building simulation model and analysis,the principle of the device is explained.The developed calibration device prototype is used to carry out excitation test,and the test results show that the design scheme is feasible.

Key words: Dynamic torque, Inertia, Angular acceleration, Calibration
