Research on structure simulation visualization platform of a ship lift tower based on WebGL technology

In the background of digital technology applied to water conservancy and hydropower engineering, a structural simulation visualisation platform is developed to realise intelligent simulation and improve visualisation and data interaction capabilities in a digital upgrade project of a ship-lift tower column structure of a ship-lift. The platform adopts WebGL technology to redraw the finite element mesh model on the web side; provides cloud map and deformation animation rendering functions for displaying pre and post-processing data; and studies finite element data processing, model faceting and cloud map rendering optimisation techniques for efficient rendering. The platform has been well applied in a ship-lift digitisation project. The visualisation function can be used for common structural analysis, and monitoring and comparison functions are developed based on the platform interface to improve the analysis of structural safety by operation and management units. The technology can be used in other simulation and visualisation platforms for water and hydropower engineering structures.
