全自动可调角度的随动测力装置设计

火箭弹作为一种武器,其尾翼多采用折叠翼片。翼片在展开的过程中,其摩擦力是重要参数,对每个翼片的摩擦力需要进行测量并记录。针对火箭弹折叠尾翼的测力要求,设计出了一种全自动随动测力装置。此装置的夹紧钳可自适应夹紧较复杂的折叠翼翼面,以提高夹紧可靠性;随动测力装置可沿着折叠翼展开轨迹,准确测出折叠翼展开过程中的实时拉力值。通过对夹紧钳进行理论计算与静应力分析,其结果基本一致,表明此夹紧钳结构合理。

Design of Automatic Adjustable Angle Follow-up Force Measuring Device

As a weapon,the tail fins of rocket usually adopts folding fins.In the process of expansion,friction force is an important parameter.So it is of necessity to measure and record the friction force of each fin.Aimed at the structure and force measurement requirements of the folded tail fin of rocket,an automatic following force measurement device was designed.The clamping clamp of this device was adapted to clamp the complex wing surface of folding wing to improve the clamping reliability.The following force measuring device was intended to measure the real time tension of the folded wing along the expansion path.The theoretical calculation and static stress analysis of the clamp were basically consistent,which verifies the fact that the clamp structure is reasonable.
