Abstract

The invention relates to a component partitioning simulation method based on lunar probe landing mechanical environment prefiguration, belonging to the technical field of deep space exploration. The invention provides a reasonable component partitioning simulation method based on the requirement of lunar probe landing mechanical environment prefiguration. The method can orderly and efficiently carry out the work of finite element analysis and provide convenience for the subsequent work of mechanical environment prefiguration, so that the defect that finite element modeling of a complex aerospace structure is tedious and fallible is avoided, and integrated analysis of component partitioning, finite element analysis and mechanical environment prefiguration is achieved. According to the component portioning simulation method, component partitioning can be carried out on a complex lunar probe according to the requirement of lunar probe landing mechanical environment prefiguration, so that the obtained result can be orderly stored; furthermore, modeling component partitioning keeps consistence with component partitioning required by mechanical environment prefiguration analysis, so that the problem of disordered result file management is avoided.

Description

technical field [0001] The invention relates to a component division simulation method for lunar probe landing mechanical environment prediction, and belongs to the technical field of deep space exploration. Background technique [0002] The moon soft landing technology is a key technology of my country's lunar exploration project. In order to ensure the safety of the equipment and personnel carried on the lunar probe and make the lunar probe land on the surface of the moon smoothly and smoothly, it is necessary to carry out strict dynamic analysis and research on the soft landing process on the moon. [0003] When the lunar probe enters the lunar orbit, it will go through the power descent stage. At the end of the stage, the lunar probe will freely fall to the lunar surface from a height of about 4m. During the landing impact process, the lunar probe needs to experience a transient impact load. Whether it can withstand this mechanical environment is the key to the success ...

Problems solved by technology

However, in the predictive analysis of the mechanical environment of the lunar probe landing, it is necessary to perform secondary calculation processing on the response results of different components, which requires grouping and calculation of the extracted results according to specific components. In the current method, the division of components during modeling The basis is arbitrary, and such division of components may be inconsistent with the grouping calculation of the subsequent result post-processing components, which leads to confusion in the management of result files and errors, so that results cannot be processed conveniently and quickly by component
