摘　　要：目前弹性体的解耦大多以静态实验标定的方法求解,而缺少对弹性体建模的理论分析。以六维力传感器弹性体中的上E型膜为研究对象,根据其结构和约束条件建立力学模型,通过薄板弯曲理论推导出上E型膜在仅受Z方向载荷FZ时受迫振动过程中任一瞬时的动扰度表达式,并求出动态应变输出。仿真实验表明理论推导与实际情况较吻合。At present, elastic decoupling of six-axis force sensor is mostly achieved by the static calibration experiment, but there are few analysis of elastic body modeling theory. Taking E-type membrane of six-axis force sensor as study object, according to its structure feature and boundary conditions for the establishment of mechanical model, through the thin plate bending theory, this paper deduced the dynamic disturbance degree expression of E-type membrane in any instantaneous process of forced vibration, only by the dynamic load FZ in Z direction effect, and gave the dynamic linear strain and simulation experiment. This paper provided theoretical and data foundation for the subsequent elastomer dynamic decoupling .
