基于立姿射击的抵肩力统计分析

Statistical Analysis of Firearms′Shoulder-Force Based on Standing Position Fire

介绍了立姿射击的抵肩力统计测量的意义及采用双剪切梁式应变测力传感器测量抵肩力的系统组成 ;详细讨论了获得的原始抵肩力信号 ,并探讨了加速度修正方法及抵肩力信号滤波截止频率的选择依据。在大样本统计实验的基础上 。

The significance of shoulder force statistical measurement is explained,and a sys- tem with double- shear beam stain gage force transducer for measuring the shoulder- force is introduced.Based on the analysis of originally measured shoulder- force signals,a method for modifying the acceleration and the basis for choosing the cut- off frequency for filtering the signals are given.According to the statistical experiments with large sample size,the regular- ity in the shoulder- force reflecting the Chinese people′s physique characteristics is studied.
