摘要：飛行模擬轉(zhuǎn)臺是航空航天仿真試驗的重要設(shè)備之一，近年來仿真技術(shù)的發(fā)展對飛行模擬轉(zhuǎn)臺提出了更高的要求，同時也促進(jìn)和飛行模擬轉(zhuǎn)臺的開發(fā)。飛行模擬轉(zhuǎn)臺是具有重大經(jīng)濟(jì)價值和國防戰(zhàn)略意義的高精尖實驗設(shè)備，它是在實驗室條件下模擬飛行器或?qū)椩诳罩酗w行姿態(tài)半實物仿真的有力工具，它和目標(biāo)發(fā)生裝置組合在一起模擬導(dǎo)彈跟蹤目標(biāo)的過程，可以真實地模擬出導(dǎo)彈等飛行器在空間的各種姿態(tài)和動力學(xué)特性，從而對其傳感器件、控制系統(tǒng)和執(zhí)行機(jī)構(gòu)等硬件設(shè)備的性能加以測試和評價，為飛行器的研制、改進(jìn)和再設(shè)計提供各種參考依據(jù)。它的性能指標(biāo)直接關(guān)系到飛行仿真結(jié)果的逼真度。隨著當(dāng)前國際形勢的日益嚴(yán)峻和我國現(xiàn)代軍事技術(shù)的不斷發(fā)展，對模擬轉(zhuǎn)臺的精度要求不斷提高。作為一種高精度的運(yùn)動仿真設(shè)備，其臺體動態(tài)特性直接影響到轉(zhuǎn)臺動態(tài)仿真的可靠程度。在設(shè)計階段對機(jī)械臺體進(jìn)行動態(tài)特性分析和優(yōu)化設(shè)計，尤其是對框架等結(jié)構(gòu)支撐部件的動態(tài)特性研究和結(jié)構(gòu)優(yōu)化設(shè)計十分重要。本文主要介紹液壓模擬轉(zhuǎn)臺，包括設(shè)計特點和主要性能，并對主要指標(biāo)的測試情況作了簡單介紹和分析。

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 evaluation, 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.
