【 摘 要 】

The lumped parameter model of this novel MR Mount was established and nonlinear mathematical state equations of bond graph model for the MR mount is developed. Finally, its dynamical performance is analyzed and predicted. The results show that the dynamic stiffness (400N/mm) in the frequency range 0-20Hz and the dynamic stiffness (500-700n/mm) in the frequency range 0-25Hz are effective for the isolation of road and powertrain source excitation.
