摘要

A time domain simulation model for torsional vibrations of a work boat propulsion system was developed. It is suitable for both linear and nonlinear cases. The model is a combination of the Bond graph method and SIMULINK{dollar}rm sp{lcub}TM{rcub}{dollar} software. A typical work boat propulsion system is used as an example to illustrate the simulation procedure. Although the program is mainly designed for work boat torsional vibration simulation, it has application for a general dynamic system.; A dynamic test stand for testing elastic couplings was designed and fabricated. The dynamic properties of the coupling were measured. The test data were analyzed. The results show both stiffness and damping are strong functions of mean torque, vibratory velocity and temperature. The test results are presented in two different ways for the convenience of the user. One form is suitable for traditional frequency domain analysis. The other form is for time domain simulation.
