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 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.
