摘　　要：静电传感器的感应与监测性能与其特性参数相关,利用理论方法进行数学建模与计算是一种较有效的方法,但模型构建的难度较大。因此,采用基于有限元的建模和仿真研究方法,该方法可以对润滑油路静电传感器结构材质进行设定且无须通过复杂的理论公式推导。仿真结果表明:空间灵敏度在探极感应面中心区域内变化较明显;传感器效率随探极长度与直径比值增大而增大。仿真结果与理论模型计算结果变化趋势相一致,且更精确直观,对后续使用有限元方法研究结构更复杂的静电传感器的性能提供参考。The induction and monitoring performance of electrostatic sensor is related to its characteristic parameters.Using theoretical method for mathematical modeling and calculation is an effective method, but it is difficult to build the model.Therefore, the finite element-based modeling and simulation research method was adopted, which can set the structural material of oil-line electrostatic sensor without deriving the complex theoretical formula.The simulation results show that the spatial sensitivity changes obviously in the central area of the probe sensing surface, the sensor efficiency increases with the increase of the probe length to diameter ratio.The simulation results are consistent with the change trend of the theoretical model calculation results, and are more accurate and intuitive, which provides a reference for the subsequent use of the finite element method to study the performance of electrostatic sensors with more complex structures.
