Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the following examples are based on the premise of this technical solution, and provide detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0037] The hydraulic mechanical equipment described in this embodiment specifically refers to the hydraulic mechanical equipment for degreasing sewage. Since the density of oil pollution is lower than that of water, the oil pollution will float on the upper surface of the water and follow the water to flow downstream, such as Figure 18 As shown, AB in the figure is a hydraulic mechanical equipment for degreasing sewage composed of floating bodies and diversion tanks connected in series. According to the characteristics of oil and water, the existing treatment method basically adopts the method of interce...

Abstract

The invention discloses a method for optimizing the design of a floating body of hydraulic mechanical equipment. Firstly, the design parameters and target parameters of multi-objective optimization are determined, and within the scope of the design parameters, the design parameters are discretized by using a uniform test design method and AQWA, and Sample extraction and refinement. Afterwards, on the basis of using the ANN algorithm to construct the response surface, the MOGA algorithm is used for global optimization. Finally, the pareto front is obtained, and the optimal design parameters are obtained on this basis. It is proved by experiments that the optimized design of the present invention has good effect.

Description

technical field [0001] The invention relates to the technical field of design methods for floating bodies, in particular to an optimal design method for floating bodies of hydraulic mechanical equipment. Background technique [0002] At present, the research on the optimal design method of the floating body of hydraulic mechanical equipment mainly focuses on the optimization of the structural strength, consumables and volume of the floating body itself, or the optimization of the hydrodynamic performance of the large-scale marine structure floating body, and most of them are single-target water. Dynamic performance optimization. However, there is no effective method for multi-objective optimization of hydrodynamic performance of small-sized floating bodies in inland rivers. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide an optimal design method for the floating body of the hydraulic mechanical equipmen...
