BIM-based universal modeling method for mechanical model

Abstract

The invention discloses a BIM-based universal modeling method for a mechanical model. The method comprises the following steps of 1, establishing a standard library for converting a BIM model into a mechanical finite element model; and 2, establishing an initialized mechanical finite element model on the basis of the standard library; wherein the standard library comprises a standardized componentfamily library and a simulated component family library, component attributes of the standardized component family library comprise variable parameters, invariant parameters, finite element modelinginstruction codes and dead load, and the simulated component family library comprises an additional constant load family, a live load family and a boundary condition family. Forming finite element modeling instruction codes and self-weight loads of the BIM model and the components based on the standardized component family library; and giving additional constant load, live load and boundary conditions to the BIM model based on the simulation component family library. According to the method, the conversion problem from the BIM model to the mechanical model is solved, and the efficiency and precision of establishing and optimizing the mechanical finite element model can be improved.

Description

technical field [0001] The invention relates to a general modeling method of a mechanical model based on BIM, which belongs to the technical field of BIM technology information construction. Background technique [0002] BIM technology refers to building information model technology, which has two key factors: model and informatization. The model refers to the three-dimensional space model, and the informatization refers to various information carried in the three-dimensional space model, including component attribute information such as component material properties, component size and shape in the model, as well as progress information and quality information involved in engineering construction, etc. Process data information, etc. Building a 3D model based on BIM forms a key information carrier covering the entire life cycle of architectural design, construction, operation and maintenance, which is of great value to engineering construction. The mechanical model general...
