Concentric electrode static electric field simulation device and usage method thereof

Abstract

The invention discloses a concentric electrode static electric field simulation device and a usage method thereof. The device comprises a base, a longitudinal movement mechanism, a lateral movement mechanism, a probe mechanism and a concentric electrode plate. The longitudinal movement mechanism comprises two longitudinal guide rails which are fixed on both sides of the base in parallel, a longitudinal slide block is slidably mounted on each longitudinal guide rail, and a longitudinal scale is fixed on each longitudinal guide rail. The lateral movement mechanism comprises a transverse guide rail, the both ends of the transverse guide rail are respectively fixed on one longitudinal slide block respectively, the lateral guide rail is slidably provided with a lateral slide block, and a lateral scale is fixed on the lateral guide rail. The probe mechanism is fixed on the lateral slide block; the concentric electrode plate is fixed at the center position of the base; and the probe mechanism can realize the free movement in the longitudinal direction and the lateral direction and the data measurement. The usage stability and reliability of the instrument is improved.

Description

[0001] Technical field: [0002] The invention relates to the field of experimental teaching instruments, in particular to a device for simulating an electrostatic field of concentric circular electrodes and a method for using it. [0003] Background technique: [0004] Understanding and mastering the electrostatic field distribution around the charged body is very important for some scientific research and engineering technology, but it is generally difficult to calculate the electrostatic field distribution with theoretical methods, and it is also quite difficult to measure the electrostatic field directly. The measurement of the electrostatic field generally uses an analog method , the electrostatic field is simulated by a steady current field, and the potential distribution of the electrostatic field is determined by measuring the potential distribution in the constant current field. In the university physics experiment course, the experiment of "simulation method depicting...
