| Abstract: | The measuring process of the impact weighers is analyzed by experiments.Based on the experimental data,the transfer function is verified and the mathematical model is set up for the impact weigher.Afterwards,the instantaneous impact signal,continuous impact signal and discontinuous impact signal are simulated with simulink toolbox,the precision of measurement of the impact weigher is analyzed under different signals.The experimental results indicate that measurement following the dynamic characteristic of the impact weighter is of great significance to guarantee the correctness and the credibility of the measurement.Several advices are proposed for the industrial application of impact weigher. |
