The invention discloses a ship propulsion shafting whirling vibration and twisting vibration
simulation experiment device. The experiment device comprises a pedestal, a motor, an inter-
axial transmission mechanism, a whirling vibration shaft and a twisting vibration shaft; the motor is fixed to the pedestal, the whirling vibration shaft and the twisting vibration shaft are in parallel arranged above the pedestal; the inter-
axial transmission mechanism is used for driving said two shafts, and comprises a combination wheel and inter-axial gears, and belts, gears or chains are driven as needed; the whirling vibration shaft is provided with an alignment
flange, a counterweight disc, an adjustable displacement bearing and measurement interfaces; the twisting vibration shaft is provided with a shock excitation motor, universal joints, an
universal joint angle control apparatus and measurement interfaces, and the rotor of the shock excitation motor is connected to the shaft and used for simulating and generating twisting vibration. The experiment device is simple in structure and strong in pertinence, and can be applied to
simulation study of shafting whirling vibration and twisting vibration and
impact of shafting alignment status and transmission manner to whirling vibration and twisting vibration.
