Research and Implementation of Vehicle Virtual Test System Based on Product Performance Prototype

In order to make full use of the performance prototype model in the development of the spacecraft, this paper put forward the design of the vehicle virtual test system based on product performance prototype. Through the sub-system division and work flow design of the test base database, test data management, verification assistant, virtual test application, the system can support the whole process of virtual test. The system breaks through the key technology of object-oriented management of experimental data and modeling of test flow, and is implemented based on the virtual test platform VITA. Using this system, several typical application is carried out in the development of multiple aircrafts.
