Description
Technical Field
The invention relates to the field of data management, in particular to a mechanical interface data management method and system based on a model. And more particularly, to a method for defining, extracting and managing data in a three-dimensional model for satellite mechanical interface data.
Background
The single-machine equipment product is an important component of the satellite and also an important design input of the overall configuration layout design, and the design state and the design quality directly influence the subsequent design and application. The single machine equipment has the characteristics of wide distribution, various subsystems and the like.
The subsystem unit submits an interface data sheet and a three-dimensional model as design input of a general design unit, when the model and the form are received, whether data of two sets of data sources are consistent needs to be repeatedly checked, and the problems that information of a cross overlapping part of the model and the interface data sheet is inconsistent, model lightweight modeling is not standard and the like are often found. This problem causes multiple iterations of the inter-unit design, causing unnecessary quality risks, and reducing design efficiency. The main points are as follows:
(1) equipment lightweight modeling non-specification
Because the digital implementation specifications are different, the specifications of models in different institutions are different, the related standard specifications of the subsystem production unit to the overall unit are not recognized sufficiently, and the submitted three-dimensional model can not meet the related requirements of the overall unit easily, so that unnecessary iteration caused by the normalization of the three-dimensional model is easily generated, and the design period is prolonged;
(2) tabulated IDS form fill-in difficulties
At present, partial information in an IDS form is difficult to fill, and the partial information can be sequentially filled after being measured one by one through a three-dimensional model, such as the length, width and height of equipment, the position of a mounting hole and other information. In each design iteration or design change, in order to ensure the design quality, the partial information needs to be re-measured and then confirmed again;
(3) repetitive design input source
When the model and the form are received, two sets of repeated interface data exist, whether the data of the two sets of data sources are consistent needs to be repeatedly checked, and the problem that information of a single cross overlapping part of the model and the interface data is inconsistent is often found, so that multiple iterations are caused, unnecessary quality risks are caused, and the design efficiency is reduced.
