The invention relates to the technical field of railway engineering, and discloses a BIM-based dynamic simulation method for wrist arm pre-configuration, comprising: acquiring wrist arm data, drawing a two-dimensional wrist arm diagram, establishing a wrist arm three-dimensional model, wrist arm dynamic simulation, and data processing The steps are: establishing a locking relationship by drawing a pre-configured two-dimensional drawing of the wrist arm; creating a suitable component model; setting parameters to drive the change of the two-dimensional drawing; placing the component model on the two-dimensional drawing, and the change of the two-dimensional drawing drives the change of the three-dimensional model; The 3D model checks the correctness of the output and input data, uses the reference lines, reference planes and the mutual constraints of the components of the BIM software, and sets the parameters to achieve the result output without the calculation process, eliminating the tedious calculation process and simulating the actual installation on site Scenarios, improve the installation accuracy, reversely verify the correctness of the output data through the three-dimensional model diagram, and verify the correctness of the input parameters, basically avoid the production and application of wrong data, reduce the scrap rate, and save production costs.
Description
technical field [0001] The invention relates to the technical field of railway engineering, in particular to a BIM-based dynamic simulation method for wrist arm pre-configuration. Background technique [0002] At present, in the construction process of the electrified railway catenary, the pre-configuration of the wrist arm is an important process, which is of great significance to the safe and stable operation of the traction power supply system. At present, the pre-configured data of the wrist arm is calculated by the Excel table formula, the coordinate method and the development software, and the result data is output in the form of a table. The correctness of the data is difficult to intuitively determine, and the correctness of the pre-configured data of the wrist arm can only be verified through two-dimensional CAD simulation and on-site pre-installation. [0003] There are two situations in the calculation results. One is that the data is inaccurate. After the pre-co...
