ON THE PROBLEM OF HEIGHT ADJUSTMENT OF THE ACTIVELY CONTROLLED DRIVER‘S SEAT VIBRATION ISOLATION STAND
Keywords:
vibration isolation stand, height adjustment, conducting mechanism, pneumatic springAbstract
Every driver’s seat vibration isolation stand is supplied with height adjustment. In
the case of a standard seat vibration isolation stand (passively suspended), such
adjustment is realized by the position mechanical controller. Any change in seat
height results also in the change of the position of the working point of the
pneumatic spring and the reduced mass or reduced inertia moment of the
conducting mechanism are changed as well. This further results in the change of its
natural frequency, transmissibility characteristics etc. These dependencies are
analysed in the paper using an actively controlled driver’s seat vibration isolation
stand with scissor mechanism.
