This invention relates to the field of vehicle OTA upgrade testing technology, and discloses a network simulation system and testing method for vehicle OTA upgrade testing. The system includes a cellular communication simulation network, a programmable attenuation and channel simulation device, and a user terminal. The cellular communication simulation network includes an access network, a bearer network, and a core network. The access network deploys a base station controller and multi-band base stations. The radio frequency signal output from the access network is connected to the test environment via the programmable attenuation and channel simulation device. The user terminal sends commands to the base station controller for base station activation and deactivation configuration, and base station transmit power adjustment. The user terminal also sends commands to the programmable attenuation and channel simulation device for channel simulation mode control and signal strength adjustment control. Finally, the user terminal sends commands to the bearer network device for network transmission link parameter configuration. This invention can simulate various typical network scenarios through parameter configuration, enabling non-road testing of OTA upgrades.

This invention proposes a bidirectional synchronous high-speed imaging and diagnostic system for electric thruster plasma oscillation. It comprises a vacuum chamber, an electric thruster, a vacuum chamber observation window, electric thruster plasma, a reflector assembly, a side-viewing optical path, a high-speed camera, a data processing system, and a high-speed camera's imaging range and a front-viewing optical path. The electric thruster, vacuum chamber observation window, and reflector assembly are bolted together inside the vacuum chamber. The electric thruster plasma is generated by the electric thruster and adheres to its outer surface. The side-viewing and front-viewing optical paths are formed by the reflector assembly. The high-speed camera is placed outside the vacuum chamber, with its imaging range directly facing the vacuum chamber observation window to capture the side-viewing and front-viewing optical paths. The electric thruster and its plasma are the subjects of the imaging. Compared to traditional bidirectional synchronous high-speed imaging, this invention establishes a bidirectional optical path to simultaneously introduce images of the side and front of the electric thruster into the lens of a single high-speed camera, requiring only a single high-speed camera. This reduces the financial and time costs of experiments and improves research efficiency.

The application is an open fan full-range working characteristic expansion method based on skeleton characteristics, belonging to the field of open rotor engine; the method introduces a skeleton characteristic representation system with loss coefficient as the core to solve the problem that the efficiency in the representation of traditional propeller characteristics has singular points in the autorotation state, leading to the collapse of cross-condition numerical simulation calculation. By defining the work coefficient, pressure coefficient and loss coefficient, and based on the blade element theory to determine the ridgeback point and its existence condition, the ridgeback characteristics describing the characteristic change law of ridgeback point and the non-ridgeback characteristics describing the deviation law of non-ridgeback point are constructed. Finally, by combining the ridgeback characteristics and the non-ridgeback characteristics, the known local working condition characteristic data is continuously and smoothly expanded to the full working range including braking, autorotation and windmill state. The application fundamentally eliminates the numerical singular points in the characteristic curve, realizes the stable simulation and high-performance expansion of the open fan in the full working condition.
