| Abstract: | A semi-active engine mount(SEM) with switchable stiffness decoupler was designed and manufactured,and its dynamic characteristics were measured with MTS 831 servo-controlled hydraulic test rig.A linear lumped parameter(LP) model for the SEM was proposed.The dynamic stiffness and loss angle of the SEM under high amplitude and low frequency excitation were calculated using the linear LP model.The results had a good agreement with the test data,which validated the proposed LP model.Some applications of SEM for... |
