Experimental and Analytical Study of Secondary Path Transfer Function in Active Hydraulic Mount with Solenoid Actuator

The active hydraulic mount with solenoid actuator (AHM-SNA) does not require permanent magnets, is of low cost, and has attracted wide attention. This paper focuses on each link the secondary path in AHM-SNA, transfer functions (TFs) were studied one by one, a simple efficient expression for total discussed. First, based mathematical model inertia track decoupling membrane, TF from force to output at frame side was analyzed, results show that constant mid-frequency band. Second, geometric parameters cone air gap actuator, it obtained square current also constant; relationship frequency twice harmonic frequency, full-wave-rectified introduced. Utilizing fact second component main component, concluded then Finally, two sets experiments as excitation carried out, analytical conclusion verified proportional convenient control algorithms.
