Embodiment 1

[0032] A hierarchical design method for a schematic diagram of a marine transmission device, including the construction of a characteristic unit of the transmission device, and the construction of a first-level topology model and a second-level topology model. The steps of the method are as follows:

[0033] Step 1. Construct the transmission unit library of the marine transmission. The transmission feature unit includes key components (main engine, propeller, bearing, coupling, shaft, gear box, and components used for the internal structure of the gear box: gears [herringbone gears, spur gears, helical gears, bevel gears, planetary gears] Gear train], clutches, bearings, shafts).

[0034] Step 2, first-level drag-and-drop topological relationship modeling. The first-level drag-and-drop topological relationship modeling mainly establishes the connection relationship among main engines, propellers, gearboxes, etc., and determines the number and form of main engines (steam turb...

Embodiment 2

[0063] The purpose of the present invention is to solve the problems of lack of design means, single modeling means, and insufficient comparison of multi-scheme modeling schemes in the conceptual design of ship transmission devices, and propose a hierarchical (first-level, second-level) schematic design of ship transmission devices method.

[0064] The present invention realizes the construction of the first-level and second-level models of the transmission system mainly through drag-and-drop modeling, so as to determine the topological relationship between each unit from power input to power output in the concept design stage of the transmission system. The main idea is to face the conceptual design stage of the transmission system. Without considering the spatial layout and structural constraints of the system, determine the number of transmission stages and transmission forms of the transmission system and establish a topology model of the transmission system. Design provid...

Abstract

The invention belongs to the technical field of product design, and particularly relates to a hierarchical ship transmission device sketch design method. According to the method, the problem of rapid design of the transmission system is solved by using the idea of configuration design, and a design idea is provided for rapid design of the transmission system facing the topological relation model. According to the method, the transmission unit library is constructed, so that accumulation and reuse of design knowledge and experience of the transmission system are realized; a transmission system scheme can be quickly determined through dragging type topological relation modeling, and a top-down concept modeling mode is supported; the first-level modeling is based on the overall design target (power, rotating speed and the like), model constraint and the like of the transmission system for solving, the second-level modeling is based on the local design requirement transmitted to the gear box and local model constraint for solving, the design difficulty can be reduced through the hierarchical modeling method, and through the modeling analysis of the topological relation model, the modeling efficiency is improved. A transmission system design scheme can be quickly obtained, the design efficiency is greatly improved, and a foundation is laid for subsequent independent innovative design.

Description

technical field [0001] The invention belongs to the technical field of product design, and in particular relates to a hierarchical design method of a schematic diagram of a ship transmission device. Background technique [0002] The performance of a ship depends largely on the quality of its drivetrain design. The general principle of the marine transmission device is to transmit the power from the prime mover to the propeller through different transmission relationships to meet the navigation requirements under different working conditions. Although Chinese researchers have made great progress in the design of ship transmission system in recent years, there is still a big gap with the advanced level of foreign countries. At present, commercial computer-aided design software still has the defects that it does not support top-down design, does not support conceptual modeling, and cannot quickly compare and evaluate multiple schemes. Contents of the invention [0003] The ...
