称重传感器精确标定研究

摘要

In order to accurately reflect the weighing values of propellant weighing output value in an propellant automatic weighing machine, research on accurate calibration about load and weighing cell. Use function chain neural network method to calibrate functional relation about weighing detection value of weighing system or actual heaviness. Accuracy of calibration weighing system less than or equal to 1%, it meet production requirement.%一种发射药自动称量机为使发射药称重输出值能精确地反映称重值，对称重传感器精确标定进行研究。采用函数链神经网络法对称重系统称重检测值与实际重量值之间的函数关系进行精确标定，通过标定的称重系统精度≤1%，满足实际生产需要。
