Embodiment 1

[0049] The implementation steps of the hydraulic performance of the submersible pump: enter the virtual test module of the hydraulic performance of the submersible pump through the portal system, use the general finite element software Ansys as the platform, and go through the following steps:

[0050] (1) Virtual test calculation management. In the virtual test interface, the user first needs to select the working directory, and all the completed submersible pump hydraulic performance virtual test tasks in the table are automatically updated in the table, and each subsequent virtual test task is placed in the Under this directory, it also serves as the homepage of the virtual test of the hydraulic performance of the submersible pump;

[0051] (2) Test bench model import. In the test bench model import interface, it supports the function of importing the local model of the test bench and the import function of the database model of the test bench. On the premise of importing th...

Embodiment 2

[0062] The implementation steps of the vibration performance of the submersible pump: use the general finite element software Ansys workbench as the platform, import the submersible pump model (including roof, pipe string, pump head and other components) in the DesignModel module, and check the material density, Yang Modulus and other parameters are modified. Tolerances between parts are adjusted through manual contact settings. Set the mesh size between different parts to discretize the submersible pump model. According to the mechanical characteristics of the crane, the boundary constraints and load addition are carried out, so as to establish the final vibration simulation model of the submersible pump.

Embodiment 4

[0064] The implementation steps of STC valve speed regulation performance of submersible pump: enter the process interface, select the working path and create a new virtual test; use the multi-field general CAE platform MWorks as the calculation platform, import the STC valve model required for this calculation from the local or database; Modify the control parameters and save them, set the sweeping parameters and solution parameters, and then start the calculation program; add the physical test data after the calculation is completed, check and compare the data and result curves of this virtual test; analyze the error of this virtual test and Give an evaluation, if the error is large, you can choose to modify the parameters and recalculate; view the final result curve and generate a report.

Description

technical field [0001] The invention relates to the technical field of marine equipment service systems, in particular to a virtual test application service system and method for marine electromechanical equipment. Background technique [0002] Existing marine electromechanical equipment needs a lot of simulation analysis work in the design simulation, which is highly specialized and has a wide range of expertise, involving hydraulic performance, load performance, speed regulation performance, active wave compensation performance, vibration performance and computer software, etc. specialized. In the design process, multiple rounds of design iterations and optimizations from simple to complex, and a large number of scheme comparisons consume huge human resources and carry out long-term and high physical test costs. At the same time, due to subjective and objective factors in each link The resulting experimental error makes the final result require a high safety factor to ens...
