[0002] With the continuous development of China's aviation industry, the demand for pilots is increasing, and if real aircraft is used for training each time, not only the cost is high, but also it cannot be trained under extreme conditions, which greatly increases the cost of pilot training. The aircraft simulator can reflect the various conditions of the aircraft in the air in real time through specific simulation equipment, so that the pilot can complete various training on the ground, and can not be restricted by weather, environment and climate, greatly reducing the training cost and shortening the training cycle, while ensuring the safety of the pilot to the greatest extent during training. The operating load system is a key component of the simulator, which aims to provide the pilot with consistent operating feeling as the real aircraft, and its performance directly affects the user experience of the operator.

[0003] The technical bottleneck of traditional mechanical hydraulic system, traditional hydraulic operating load system relies on fluid transmission, and has problems such as response delay, high energy loss, complex maintenance, etc., which is difficult to meet the demand of high-precision real-time force feedback. The hydraulic system is sensitive to temperature and sealing, and is prone to performance degradation due to leakage or oil pollution, especially in harsh scenes such as aviation simulation, which has insufficient reliability. Force simulation distortion: mechanical structure friction, inertia force compensation is not sufficient, etc. cause the pilot to feel the deviation between the rod force in the simulator and the real aircraft, which affects the training effect. Therefore, an electric operating load device is urgently needed. UTILITY MODEL CONTENT
