| 内容記述 | In this report the longitudinal, torsional and two directions of lateral vibrations on the engine crankshaft system of large, low-speed, in-line marine diesel engines are numerical calculated first by the three dimensional analysis of forced vibration by the transfer matrix method, which has been developed by the authors. The torsional vibration of diesel engines has become severer with the increase of exciting force by higher pressure. Therefore, the running crankshaft is highly stressed owing to the large torsional vibration. Then, torsional viscous-friction dampers of high performance have been employed in high mean effective pressure diesel engines as a measure for vibration reduction. In this study, the authors refer mainly to the three dimensional vibration model and the derivation of the transfer equation of the analyzed marine engine crankshaft and propeller shaft system, and describe the numerical calculation method. Next, the numerical calculated results are compared with the corresponding experimental results for investigating the dynamic characteristics of the three dimensional vibrations and also the adequacy of the analytical method. As a result of the comparisons with the measured results, the following conclusions are obtained; ［1］ The numerical calculated results are approximately similar to the measured ones. From this comparison, it can be assured that the use of this three dimensional numerical calculation methods enables the estimation of the longitudinal, torsional vibrations, including the coupled vibrations, provided that the correct input data are specified. ［2］ The dynamic characteristics of the forced vibrations of the large, low-speed, marine diesel engine are made clear. |
