The invention discloses an optimized preparation method of a hydrodynamic lubrication radial sliding bearing, and relates to a preparation method of a sliding bearing, in particular to an optimized preparation method of the hydrodynamic lubrication radial sliding bearing based on a multi-objective evolutionary algorithm (MeEA) of a multi-ecological environment selection strategy, and a multi-objective optimization design of the sliding bearing is realized by adopting the multi-objective evolutionary algorithm based on the multi-ecological environment selection strategy. The method comprises the following steps: firstly, dividing a target space into a plurality of different types of ecological environments in a population evolution process; secondly, in the aspect of environment selection, preferentially considering the convergence or diversity of the ecological environment, and maintaining the overall diversity of the population later; and finally, applying the method to the optimal design of the hydrodynamic lubrication radial sliding bearing. Through the algorithm optimization, the effect of the fluid dynamic pressure lubrication radial sliding bearing after optimization design is remarkable, and a method basis is provided for improving the performance of the bearing in the actual working condition.
Description
technical field [0001] The invention relates to a sliding bearing design method, in particular to an optimized preparation method of a fluid dynamic pressure lubricated radial sliding bearing. The method is a preparation method for the optimization of hydrodynamic lubricated radial sliding bearings based on the multi-objective evolutionary algorithm (MeEA) of multi-ecological environment selection strategy. Background technique [0002] Hydrodynamic lubricated radial sliding bearings are widely used in high-speed and light-load working conditions due to their smooth, reliable and noise-free features. Sliding bearings seem to have a simple external geometry, but different shape parameter settings may have different effects on bearing performance, such as fluid friction coefficient, heat generation, and load-carrying capacity coefficient. The traditional approach to bearing design is to optimize the design through empirical methods, but this method often requires a lot of tri...
