Abstract
Marine ship gears are increasingly subject to strict requirements in terms of tooth surface load capacity, dynamic performance, vibration and noise generation, and so on. The optimization of tooth ...
Highlights
The performance of warship power rear transmission system is plural and multi-objective
Concerning the optimization minimizing tooth surface flash temperature and vibration acceleration root mean square (RMS), herringbone gear tooth surfaces of characteristic optimum modification areas in Figures 22–25 have been found, which are considered as installation error of tooth surface load uniformity (g = 12$)
In the gear pair optimization design of a warship power rear drive system, in addition to considering the fatigue strength of tooth contact and bending, it is necessary to propose the gear elastic hydrodynamic lubrication effect and the optimization problem of the multiobjective modification, such as the minimum tooth surface flash temperature and the vibration acceleration RMS. This consideration is of great significance to improve the gear pair meshing performance of a warship power rear drive system
Summary
The performance of warship power rear transmission system is plural and multi-objective (depends on multiple physical quantities). In this study, considering the installation errors and tooth surface carrying loads which are uniform or not for multi-objective optimization analysis of marine ship gears, the effect of tooth optimization with the minimum values of vibration acceleration RMS is discussed.
