Study On Photoelectric Sensor Technology Based On MRF

Magnetorheological fluid is a kind of excellent intelligent fluid materials which ismade of the magnetic particles, the liquid and additives composition. Without externalmagnetic field, magnetorheological fluid presents good liquidity of the liquid state; Inthe state of magnetic field,it will presents solid state in a short time (millisecondtimescale).The character of Magnetorheological fluid has been widely used in aviation,automotive, bridge engineering and damping control. As a kind of intelligent materials,the character of MRF has broad development prospects in intelligent sensingtechnology. At present, the magnetorheological fluid's flow character and dampingcharacter have been widely studied, but the electromagnetism characteristics of MRFare relatively researched slowly. In this paper, we will study the inductance characterof magnetorheological fluid and its magnetostrictive effect. In view of MRF's goodcharacteristic, this paper will also study the sensing technology and control technologybased on the intelligence of MRF.This paper is made of two components: one is the research of magnetorheologicalinductance and MRF's magnetostrictive effect, the other is the research ofmagnetorheological fluid sensing technology. The main research contents is as follows:One, we will research magnetorheological fluid inductance character. In thisarticle, we devised magnetorheological inductance with the magnetorheological fluidand inductance coil, deduced the magnetorheological inductance formula, designedexperiments testing the changing of magnetorheological inductance in the externalmagnetic field and the temperature, and analyzed the phenomenon of the experiment intheory. We provided a basis for the magnetic fluid inductance's application inelectronic measurement and sensing technology.Two, we will research the magnetostrictive effect of magnetorheological fluid. Wedesigned detection device of MRF's magnetostrictive effect, measured MRFmagnetostrictive effect using optical interference measuring method with highprecision, and provided a basis for the magnetic fluid inductance's application for MRFmagnetostrictive effect in intelligent sensing technology.Three, we will research MRF acceleration sensor based on magnetorheological fluid. We designed MRF acceleration sensor and the simulation analysis showed thatthe sensor can realize high precision testing of the different range of the acceleration.Four, we will study on adaptive optics platform based on MRF,by using MRFinverse magnetostrictive effect on optical platform we can judge whether the platformisfastigiate simplely and quickly.If platform is not balanced, we can get opticalplatform declining Angle through the operation.Five, we will research ant-vibration model based MRF. In this paper we used thecontrollable character of magnetorheological fluid shear strength, using piezoelectricceramics as actuator, put forward double isolation model based on the piezoelectricceramics and magnetorheological fluid. Through the theoretical analysis we arrival ata conclusion that the model has a good Isolation effect on both high frequencyvibration and low frequency vibration especially ultralow frequency vibration.
