Embodiment 1

[0060] The present invention provides a method and system for verifying a ship piping system design scheme. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although in The flowcharts show a logical order, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0061] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, figure 1 It is a block diagram of the hardware structure of a computer terminal of a method for verifying a ship piping system design scheme according to an embodiment of the present invention. Such as figure 1 As shown, the computer terminal 100 may include one or more (only one is shown in the figure) ...

Embodiment 2

[0093] Figure 5 It is a flow chart of a verification method for a ship piping system design scheme provided by an embodiment of the present invention, as shown in Figure 5 As shown, a method for verifying a ship piping system design scheme provided in this embodiment includes the following steps:

[0094] S201: Simplify the ship's piping system into a network diagram including nodes and piping;

[0095] S202: Obtain the first resistance value of the pipeline where the terminal node is located in the network diagram and the second resistance value of the pipeline where the secondary terminal node is located;

[0096] S203: Determine whether the error between the first resistance value and the second resistance value exceeds a preset threshold;

[0097] S204: If the error exceeds the preset threshold, adjust the first resistance value or the second resistance value according to the judgment result, and perform the judgment of the difference between the first resistance value...

Embodiment 3

[0103] Figure 6 It is a flow chart of a verification method for a ship piping system design scheme provided by an embodiment of the present invention, as shown in Figure 6As shown, the verification method of a ship piping system design scheme provided by this embodiment can be realized by programming in languages ​​such as Visual Basic, Visual C++, Visual C#, JAVA, etc. This method designs a function selection and parameter input interface for respectively realizing the Path resistance, flow and multi-branch piping calculation problems. Among them, the calculation process of resistance is based on the Bernoulli equation and Nicholas empirical formula. The calculation process of flow is based on the assumed initial flow, calculates the resistance value, and then compares the calculated resistance value with the given resistance value. In contrast, iteratively solve the real flow value. When calculating the multi-branch piping system, the software simplifies the complex pipi...

Abstract

The invention discloses a ship piping system design scheme verification method. The method includes the steps that a ship piping system is simplified into a network graph; a first resistance value anda second resistance value are acquired; whether or not the error between the first resistance value and the second resistance value exceeds a preset threshold value is judged; if yes, the first resistance value or the second resistance value is adjusted according to the judgment result, and the above-mentioned judgment step is executed again; if not, whether or not a penultimate tail end node isa head end node is judged; if yes, the actual flow value and the actual resistance value of the piping system are output; if not, the combination of a tail end node and the penultimate tail end node is used as a tail end node, and a new second resistance value is acquired. The invention further discloses a ship piping system design scheme verification system. By means of the method and system, parameterized calculation of the resistance and flow of the ship piping system is achieved, calculation is fast and accurate, and the calculation result can be used for assisting in piping system check and pump model selection.

Description

technical field [0001] The invention relates to the technical field of ship design and manufacture, in particular to a method and system for verifying a design scheme of a ship piping system. Background technique [0002] Ship piping system is a piping system serving the whole ship, mainly including ballast water system, bilge water system, fire protection system, ventilation sounding system and domestic water system, etc. At present, in the production design of ship piping systems, it is often encountered that the actual pressure and flow rate of the fluid in the pipeline cannot meet the design requirements, for example, the working pressure is lower than its working pressure or higher than its safety pressure. When designing a ship piping system, it is necessary to verify the designed piping system in time to judge whether it can meet the design requirements. The traditional method can only be manually calculated according to the Bernoulli equation and Nicholas empirical ...
