Abstract

The invention discloses a method and a device for measuring parameters of a micro solid gyroscope equivalent circuit. The micro-solid modal gyro equivalent circuit is formed by two branches in parallel connection, wherein one branch includes a static capacitance circuit, and the other branch is a serial-connection circuit of a dynamic resistor, a dynamic capacitor and a dynamic inductor. The device comprises a variable-frequency oscillator, two terminal networks and a detector. The variable-frequency oscillator supplies a constant current to the measurement circuit and the detector is a voltage meter and is used for detecting voltage across two ends of each terminal network when the frequency is varied. The measurement method which utilizes the measurement device and is based on a maximal output frequency and a capacitance bridge can be used for solving each parameter of the equivalent circuit. In order to improve the analyzability the micro-solid modal gyro in a driving or a detecting equivalent circuit, the method and the device for measuring the parameters of the micro-solid modal gyro equivalent circuit are very necessary to provide.

Description

technical field [0001] The invention relates to a parameter measurement method and device of a gyroscope equivalent circuit, in particular to a parameter measurement method and a device of a micro solid mode gyroscope equivalent circuit. Background technique [0002] When developing, producing and applying piezoelectric devices, the measurement of relevant electrical parameters is extremely important. Therefore, the research on the measurement methods of these parameters is very important at home and abroad. Obtaining the accurate equivalent circuit of piezoelectric devices is the basis of parameter measurement. [0003] Equivalent circuits refer to different representations of the same circuit. When a certain part of the circuit is replaced by its equivalent circuit, the voltage and current of the unsubstituted part will not change, that is to say, the part with constant voltage and current is only a circuit other than the equivalent part, so it is called "external equiva...
