摘要

A new scheme of six-dimensional force strain gages of sensor distributing and decoupling is proposed.Problems of present technologies such as complex structure of spoke,test errorand decoupling indirectly is solved by taking new distributing method and bridging form.The stress measurement principle and distributing method is described in detail,and finally the bridge form is analyzed.This method greatly reduces the workload of distributing and improved the precision,which has a good prospect of application.%提出1种新型六维力传感器的应变片布片和解耦方案.采用1种4竖梁结构的弹性体,将测量点数减少为4个,克服了现有技术存在的问题,即应变片数量多、测量误差大以及软件解耦不容易解决实际测量时轮胎的压偏情况的问题.本方法以二向应力测量原理为基础,通过在4个测量点布置2α角度的8个测量片,组成与测量点正应力、剪应力相对应的电桥,最后对桥路进行了分析.该方法使传感器的布片工作量大大减小,提高了传感器精度,具有较大应用前景.
