摘要
在一般的十字梁变形筋腕力传感器的理论基础上,提出一种新的改进方案。除去了对腕力传感器精度影响较大和产生耦合的敏感部件,使结果输出更加简单直接。使用这种改进后的结构可以消除各维度受力变形之间的耦合(干扰)。文章对改进后的模型进行理论计算和有限元仿真分析,并对理论和仿真结果进行了对比。为更可靠的腕力传感器提供了结构基础。
Based on the general cross beam wrist force sensor rationale, the article advanced one kind of new improved sensor structure. The new structure removed the floating board which influence the sensor performance deeply, and realized structure simplification; moreover eliminated the coupling (cross-talk interference) between the dimension. Then, the article carry on the theoretical calculation and the finite element simulation aimed at the new structure, and contrast the result which carried on to the theoretical calculation and the simulation result. The article provided the structure foundation for the more direct reliable wrist force sensor.
