In order to make full use of advantages of giant magnetostrictive material and to improve output characteristics of giant magnetostrictive actuator, displacement magnifying mechanism is designed based on flexible hinges. The design parameter of the flexible hinges and strength of material of flexible hinges are calculated. Based on the analysis and comparison, the statics and dynamics analysis was carried on by analytic method and ANSYS12.1 software,the input stiffness, magnifying multiple and the relationship between output displacement and load are calculated,and the stress analysis shows that the maximum stress of magnifying mechanism is less than the maximum allowable stress of materials. The resonance frequency,vibration modes and harmonic response of the mechanism were resulted by Finite element method, and the dynamics parameters of system are get.

In this paper, an electro-hydrostatic actuator driven by dual axial-mounted magnetostrictive material rods-based pumps (MMPs) with a new type of active rectification valve is designed in the current study. Based on flow distribution of the active rectification valve and driving energy provided by two MMPs, the actuator can output continuous and bidirectional displacement. By establishing a mathematical model of the actuating system, using simulation techniques, the change rule of hydraulic cylinder’s motion state caused by different driving signals are studied and analyzed. Test equipment platform is constructed in the laboratory to test the output characteristics and confirm the feasibility of the new concept. The experimental results indicate that the maximum flow rate can reach approximately 2.7 L·min−1, while the operating frequency is 180 Hz.

A new bone conduction pronunciation vibrator with a bow-type structure is proposed based on the excellent characteristics of the giant magnetostrictive material (GMM); The theoretical derivation of displacement amplification ratio is carried on based on the elastic mechanics theory; And the theoretical result is simulated in magnetic-structure coupling field through ANSYS; Eventually the actual output displacement is measured using some equipment such as the laser displacement sensor. And the reliability of the theoretical derivation is vertified by the simulation and the test. All the work done in the paper provides reference and basis for the structure parameters design and optimization of the pronunciation vibrator.
