Abstract

In order to solve the shortcomings of traditional magnetic liquid acceleration sensors such as complex structure, large size and low frequency range of use, this paper designs a single-degree-of-freedom magnetic liquid acceleration sensor. The suspended magnet and the adsorbed magnetic liquid are used as the inertial mass, and the copper coil is collected to produce current for acquisition and analysis to determine the value of acceleration. Through experiments, the inertial mass vibration amplitude and current magnitude of this accelerometer are analyzed from the three influencing factors of the spacing between the inertial mass block and the fixed ring magnet, the mass size of the inertial mass block and the damping ratio. The influence of the relevant variables on the phenomena generated by the magnetic liquid acceleration sensor is studied.
