N2 - This paper presents the design, modeling, and simulation of an integrated Magnetostrictive Hydraulic Positioning Vibration Isolator (MHPVI). Targeting aerospace applications that demand high-precision and high-frequency actuation, the proposed system integrates a Terfenol-D based magnetostrictive rod with a dual-piston hydraulic chamber to achieve micro-displacement amplification. A multiphysics model coupling electromagnetic excitation, magnetostrictive strain, hydraulic transmission, and mechanical output was established. Finite element and dynamic simulations were conducted using COMSOL Multiphysics and AMESim, respectively, to analyze the system’s performance. Experimental results validate the simulation model, showing a displacement amplification ratio of approximately 12.25 with stable dynamic response. The system demonstrates strong potential for precise actuation in aerospace servo systems.
