The dynamic model of the rub-impact rotor system with an parallel misalignment was set up. By the displacement constraint between rotors, the dynamic equations was developed on the Lagrange method. Simulations show that the rotor system's low frequencies with large amplitude are 1/2, 1 and 3/2 octave spetrums. If the parallel misalignment is small, the displacement is small as the parallel becomes...
The lateral vibration of the high-speed rotation slice-disk is controlled using the hydrodynamic film and the control of the disk was studied by the finite element method and the experimental measurement. The slice-disk was meshed by elements of the fan-shaped grid. A dynamic equation of the rotation disk was established by the Lagrange equation and the theory of the hydrodynamic lubrication. The...
The planetary gear assembly is a key sub-mechanical set of the Power Shift-Steering Transmission Device (PSSTD). With the help of vibration measurement, the diagnosis issue of the needle bearing failure in the planetary gear assembly is solved. For what, there are collision pulses appearing when the Elastohydro Dynamic Lubrication (EHDL) oil film break in the needle bearing, which can be monitored...
