【摘要】 目前,研制高性能的直升机已成为我国国防建设的迫切需要。而高性能的直升机的研制涉及直升机的非线性动力学特性、非线性控制系统设计等复杂的关键技术。从计算机技术的发展情况来看,利用计算机模拟一架直升机、飞行环境以及控制系统设计是完全可能的。因此,直升机机动飞行仿真将是高性能直升机研制成功的一种十分有效的研究手段。 本论文对直升机增稳控制系统进行研究、利用现有的直升机动力学模型以及针对该直升机模型建立的增稳控制系统建立一套直升机机动飞行控制仿真软件。利用SGI工作站的多CPU并行处理和强大的图形功能对直升机数学模型研究成果进行控制、仿真验证。 论文对某小型直升机建立的动力学模型进行了简要的阐述,并且针对该直升机设计了控制增稳系统,最后,在Visual C++平台下,利用OpenGL,对直升机三维动画仿真平台进行设计与制作。从工程应用的角度出发,对样例直升机进行全机耦合仿真验证,以及直升机在不同的初始条件及干扰作用下对控制增稳系统的增稳效果进行的仿真验证等。

【Abstract】 The thesis describes the design process of 3D visualization of helicopter flight simulation. We develop the software foundation to simulate and validate the dynamics model of helicopter, in advantage of the multiple CPU and strong ability of processing graphics of SGI workstation.Now it is urgent to develop high-powered helicopter for national defence. And the development includes many complex and pivotal technology, such as non-linearity characteristic of dynamics and designing of non-linearity control system. In view of the development of computer technology, it is feasible to simulate a helicopter, flight environment and control system designing by computer. After establishing dynamics model of helicopter, we can design the control system for the helicopter, using the most advanced method. We can make our system gain the most excellent performance by repeating trial. So it is a efficient research measure to simulate helicopter mobile flight, which is used to design high-powered helicopter.The thesis expound dynamics model of a certain minitype helicopter and design control augmentation system (CAS) for the helicopter. At last, the author design and develop the 3D visualization simulation platform for helicopter, using Visual C++ and OpenGL.
