torsional vibration analysis is carried out for a marine power transmission system. The propulsion system is modeled as a flexible shaft with multiple inertias as lumped masses and shaft sections with torsional stiffness. Holzer method is employed to calculate the torsional resonant frequencies and their corresponding mode shapes.

Most shafts will transmit torque through a portion of the shaft. Typically the torque comes into the shaft at one gear and leaves the shaft at another gear. A free body dia-gram of the shaft will allow the torque at any section to be determined. The torque is often relatively constant at steady state operation. The shear stress due to the torsion
The hollow shaft and the main gear of the ball mill both adopt steel casting. The cylinder body is inlaid with wear-resisting lining plate, which has good wear resistance and smooth running. The main bearing uses the double high and low-pressure thin oil as lubrication. It is equipped low-speed transmission device which is easy to repair and start.
