The vibration suppression system (601) includes a vibration isolator (401) located in each corner in a four corner pylon mount structural assembly. The combination of four vibration isolators (401), two being forward of the transmission (607), and two being aft of the transmission (607), collectively are effective at isolating main rotor vertical shear, pitch moment, as well as roll moment induced vibrations. Each opposing pair of vibration isolators (401) can efficiently react against the moment oscillations because the moment can be decomposed into two antagonistic vertical oscillations at each vibration isolator (401). A pylon structure (615a, 615b) extends between a pair of vibration isolators (401) thereby allowing the vibration isolators (401) to be spaced a away from a vibrating body (607) to provide increased control.
