摘要

A novel sinusoidal pressure generator with low frequency(0.1 Hz $sim$ 100 Hz) based on magnetic liquid is proposed in this paper. Magnetic liquid possess both magnetism characteristic of solid magnetic material and fluidity of the liquid. The magnetic liquid acts as a reciprocating piston, when it is placed in the alternating magnetic field. Based on this, we devised a setup use of magnetic liquid to generate micro differential pressure, which varies sinusoidal and has the same frequency with the exciting current. The relation between input current and output pressure was also analyzed in this paper. Magnetic field and magnetic force is calculated. Meanwhile, the experimental platform was built for testing the performance of the setup and some experimental is performed. Both the theoretical analysis and the experiment results prove that this kind of new sinusoidal pressure generator satisfies the design demand.
