飛行模擬轉臺設計
 摘要：飛行模擬轉臺是航空航天仿真試驗的重要設備之一，近年來仿真技術的發展對飛行模擬轉臺提出了更高的要求，同時也促進和飛行模擬轉臺的開發。飛行模擬轉臺是具有重大經濟價值和國防戰略意義的高精尖實驗設備，它是在實驗室條件下模擬飛行器或導彈在空中飛行姿態半實物仿真的有力工具，它和目標發生裝置組合在一起模擬導彈跟蹤目標的過程，可以真實地模擬出導彈等飛行器在空間的各種姿態和動力學特性，從而對其傳感器件、控制系統和執行機構等硬件設備的性能加以測試和評價，為飛行器的研制、改進和再設計提供各種參考依據。它的性能指標直接關系到飛行仿真結果的逼真度。隨著當前國際形勢的日益嚴峻和我國現代軍事技術的不斷發展，對模擬轉臺的精度要求不斷提高。作為一種高精度的運動仿真設備，其臺體動態特性直接影響到轉臺動態仿真的可靠程度。在設計階段對機械臺體進行動態特性分析和優化設計，尤其是對框架等結構支撐部件的動態特性研究和結構優化設計十分重要。本文主要介紹液壓模擬轉臺，包括設計特點和主要性能，并對主要指標的測試情況作了簡單介紹和分析。

Hydraulic flight simulation turntable
Abstract: flight simulation turntable is aerospace simulation experiment is one of the important equipment in recent years, the development of simulation technology for flight simulation turntable is put forward higher request, but also promote the development and flight simulation turntable. Flying simulation turntable is significant economic value and significance of defense strategy, it is exquisite experiment equipment in the laboratory conditions simulated flying in the air or missile flight hardware-in-the-loop simulation, it is a powerful tool and plant together to simulate the process of missile tracking, can truly simulate flying in space of missile etc all sorts of attitude and dynamic characteristics of the sensor, thus, control system and enforcement agencies and other hardware equipment performance test and eva luation, the development and improvement for vehicle and is designed to provide all kinds of reference. It is directly related to the performance index of fidelity flying simulation results. With the current international situation and the increasingly serious in modern military technology unceasing development, the accuracy of simulation turntable is improving. As a kind of precision motion simulation equipment, the dynamic characteristics of the machine body directly affect the reliability of the dynamic simulation turntable. In the design phase of mechanical machine body dynamic analysis and optimal design of frame structure, especially the dynamic characteristics of the study supported components and structure optimization design is very important. This paper mainly introduces the hydraulic simulation turntable, including the design characteristic and main performance, and the main indexes of tests are introduced and analyzed.
