The invention relates to a system and a method for quickly generating a three-dimensional general assembly model of a liquid-propellant rocket engine, and aims to solve the problems of long research and development period and high labor cost caused by manual construction of the three-dimensional general assembly model and comparison of a large number of layout schemes in the overall layout stage of the liquid-propellant rocket engine. The system comprises a scheme argumentation module and a three-dimensional general assembly rapid layout module. The three-dimensional general assembly rapid layout module comprises an xml reading module, a three-dimensional general assembly model generation module and an interference checking module. The method comprises the following steps: 1, carrying out scheme demonstration; 2, generating a three-dimensional structure information xml file; 3, generating three-dimensional structure information memory data; 4, generating an assembly model, and selecting a skeleton model meeting requirements; 5, automatically assembling and generating a three-dimensional general assembly model; 6, performing interference check; and 7, outputting the three-dimensional final assembly model, and if not, returning to the step 1 to modify the demonstration scheme until the three-dimensional final assembly model is output.
Description
technical field [0001] The invention relates to a liquid rocket engine three-dimensional assembly model system, in particular to a liquid rocket engine three-dimensional assembly model rapid generation system and method. Background technique [0002] The task of the liquid rocket engine overall layout stage is to determine the general direction of the overall engine layout according to the demonstration scheme of the liquid rocket engine. The design of this stage is relatively complex, with many components, flexible decision-making, and insufficient standardization, requiring a large number of design iterations. [0003] In the current design process, it is necessary to manually build a 3D assembly model, and the overall layout requires multiple rounds of design iterations and optimizations from simple to complex, and a large number of scheme comparisons consume huge human resources, so that in the overall layout stage, it takes a long time The time-consuming research and de...
