VR and BIM based urban rail transit vehicle base modular construction simulation method

Abstract

The invention discloses a VR and BIM based urban rail transit vehicle base modular construction simulation method. The method comprises the steps of 1, building a modular database, 101, building a modular environment database, 102, building a modular basic material database, 103, building a modular assembling material database, and 104, building a modular construction equipment database; 2, constructing a three-dimensional construction scene model; 3, selecting an urban rail transit vehicle base modular construction simulation mode and performing modular simulation construction on an urban rail transit vehicle base. By determining the optimal construction process and work progress, and then determining a construction scheme of an urban rail transit vehicle base item project, the construction process is dynamically simulated, a clear and visual learning mode is provided for a constructor, the constructor can find the difference understood by the constructor between the construction process and the optimal construction process, the construction scheme is adjusted in time, and the vehicle base construction progress is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of modular construction simulation, and in particular relates to a modular construction simulation method for an urban rail transit vehicle base based on VR and BIM. Background technique [0002] The urban rail transit vehicle base is a place for the preparation, maintenance and repair of subway vehicles, and it is an important guarantee for the operation safety of the subway network. Good construction quality is the premise to ensure that the urban rail transit vehicle base is put into use, and the direct factor that determines the quality of construction is the construction process. Due to the numerous construction procedures and complex technological processes of urban rail transit, the construction schedule prepared by designers cannot accurately guide the construction process based only on the existing theoretical knowledge of construction organization estimates and past experience, and problems such as...

Problems solved by technology

Due to the numerous construction procedures and complex technological process of urban rail transit, the construction schedule table prepared by the designers cannot accurately guide the construction process based on the existing theoretical knowledge and past experience of construction organization estimates, and there are often problems such as delays in the construction period. Seriously affect the progress and quality of the project; when the construction personnel carry out construction according to the construction documents, they can only make a general plan for the construction process, cannot form an intuitive understanding of the construction scene, and fail to find problems in the construction process in time, resulting in people, objects, The waste of money has greatly increased the construction cost of urban rail transit vehicle bases; new construction personnel can enter the site after passing the systematic theoretical knowledge training. The clear, intuitive and visual learning method of the construction process of each sub-project is particularly important
