| 摘 要： | 振弦式传感器被测力与输出频率之间是一种非线性关系 ,它严重影响了传感器的测量性能。这里针对此问题提出了一种非线性补偿结构的设计方法。通过非线性补偿结构 ,可以使被测力与输出频率之间近似为线性关系。通过实际计算 ,给出了一种非线性补偿的结构参数 ,得到的结果验证了方法的可行性

| Abstract: | The nonlinear relation between the measured force and the frequency of vibrating wire sensor always severely affects the measured performance.A new design method is provided, it is possible to make measured force linear to the frequency of outputting by the means of nonlinear compensative structure.The parameter of nonlinear compensative structure can be got by the practical calculation,which confirmed the feasibility of the method. |
