    A pneumatic suspension that can adapt itself to the incoming vibration is presented in this paper. A switching control strategy between two different configurations is proposed and studied. The objective is to avoid ...

    We present an analytical model of air spring suspensions that is based on an experimental characterization. The suspension consists of three principal parts: the air spring, an auxiliary tank, and a pipe connecting the ...

    The determination of the number of cycles to failure for different stress amplitudes in concrete specimens, that is, the determination of the S--N curve, is a process that could take an extremely long period of time if ...

    A method for characterizing the magnetoelastic dependence of both Youngs modulus and damping on the magnetic field is presented. It is based on laser Doppler vibrometry and free longitudinal vibration in soft ferromagnetic ...

    The problem of unbalanced machinery isolation is tackled in this paper. The proposed solution incorporates an air suspension that can be adapted depending on the turning frequency. The system is built with three main parts: ...
