摘　　要：介绍的三分量力传感器是盒式装配式六分量天平的核心部件,该传感器弹性体采用串并联联合结构的型式,实现力的彻底分解与测量。本文分别运用传统的材料力学计算和有限元分析方法,对弹性体进行设计计算。将所得结果与传感器实测结果相比较,展现出较好的一致性。实验验证相关结论,表明设计取得良好的效果。This three-component force sensor introduced in this paper is a hardcore of the six-component box balance. The elastomeric structure of sensor accomplishes the complete force decomposition and measurement by using the form of the series-parallel combined structure. The elastic component is designed and calculated by using the traditional calculated method of the material mechanics and the finite element analysis method. Compared with the measured results of sensor, the analytical results accord with the experiments. The experiment verifies the related conclusion and shows that design has good result.
