Recently, the 2026 project application of the National Joint Fund for Innovation and Development of Natural Enterprises (CRRC) was officially launched.
This year, we will focus on rail transit, high-end equipment, new energy and other directions, and support the deep integration of cutting-edge basic research and engineering applications through two forms: integrated projects and key support projects.
It is understood that the National Nature-CRRC Joint Fund has become an important funding channel for basic research in the field of rail transit and high-end equipment.
1. Integration projects
Research on the dynamic mapping mechanism of train performance and the key technologies of virtual and real fusion verification
The integrated project focuses on the needs of digital research and development, virtual and real integration verification and efficient iteration of rail transit equipment, and includes the following research directions as a whole
- • Dynamic mapping digital model construction of vehicle performance under complex operating environment
- • Multi-scale matching and real-time synchronous operation technology of the virtual verification of digital models of trains
- • Train virtual verification confidence evaluation and uncertainty quantification technology
- • Train performance fusion verification system integration and closed-loop optimization technology
