Optimum design for rational aligning of the ship s shaft system;

Through analysis,the main causes of shaft system vibration were:problems exiseted in the foundation of generator,alignment of coupling and erection quality etc.

The shafting for turbogenerator unit has become longer due to its capacity increase,meanwhile,rotor components may have inevitable mass eccentricity with increase of service time,that would bring apparent coupled lateral and torsional vibration of the turbogenerator shaft system.

Feature-based shaft-like part 3D solid modeling and assembling;

Marine propulsion shafting is one of the main parts of marine propulsion plant.

Based on 3D CAD Solid Edge environment,the basic principle for feature-based shaft-like part design was proposed by adopting the second development and parameterized design technology.

Method of shafting aligment of ship inside dock to satisfy its request at float appearance;

The effect of high operating condition turbopump shafting status on reliability;

Dynamical Simulation and Optimization of Shafting Based on Virtual Prototype Technology;

Programming of critical speed of steam turbine rotor system;

This paper makes presentation of 125MW steam turbine structure features, elaborates calculation of alignment of HP and IP rotor and LP rotor system with cases, meanwhile describes experiences of adjustment of whole rotor system for better handling the similar problems in future practice.

An experimental study for the lateral torsional vibrations of turbogenerator set rotor system caused by electromagnetic excitations is made.

This paper is intend to demonstrate some mehtod used in the evaluation of the fatigue life expenditure of the 600MW turbine generator shafts under abnormal operation.

First,the system boundary of machines affecting the shafts,such as the guide bearings,seal,electrical and hydraulic forces,the water in the runner etc,is analyzed.
