本文简要介绍了采用双剪切梁式应变测力传感器测量抵肩力的系统组成,对测得的原始抵肩力信号作了深入的分析和讨论,提出了消除加速度影响的动态修正方法,并给出了经加速度修正后抵肩力信号滤波的截止频率的选择依据。
In this paper, the system composition of the abutment force measured by the double shear beam strain transducer is briefly introduced. The original measured abutment force signal is analyzed and discussed in depth. A dynamic correction method to eliminate the influence of acceleration is proposed. The choice of the cut-off frequency of the shoulder-force signal filter after acceleration correction is given.
