Abstract: Flight simulator has the incomparable advantages over real flight training which its structural design is the crucial to the optimization of aircraft design and improvement of the flight performance, so modeling and simulation of the research on the aircraft design is the key point for aircraft’s design. After compared with 6-DOF(Degree of Freedom) flight simulator driven by hydraulic cylinders, a kind of 3-DOF flight motion platform based on 3-RPS mechanism driven by electric cylinders under UG environment is established , and the simulation of kinematical characteristics is researched after building joints and motions for the virtual prototype under the ADAMS/View module. For given kinematics characteristic curves, the post-processing of the measurement results using ADAMS/Post Processor module is carried, to get kinematics curves of various flight attitudes. The simulation results show that the designed structure can achieve three directions of motion, such as lift, roll or pitch, and meet the requirements of the technical specifications of the civil aviation flight simulator. The processes of analysis provide effective research methods for the design of the flight simulator.

摘要: 飞行模拟器具有真实飞行训练无法比拟的优势,其结构设计是优化飞机设计,改善飞行性能的关键问题,故飞行模拟器的建模与仿真研究工作是飞行器设计的难点。通过与液压缸驱动的六自由度飞行模拟器对比分析,以3-RPS机构为基础,以在UG环境下建立的电动缸驱动的三自由度飞行模拟器运动平台模型为研究对象,在ADAMS/View模块下,对其添加约束和驱动后,进行了运动学特性仿真。对于给定的运动学特性曲线,运用ADAMS/Post Processor模块,对测量结果进行后处理,得到各种飞行姿态下的运动学曲线。仿真实验结果验证了该设计可实现升降、横滚、俯仰三种姿态的运动,且符合民航飞行模拟器的技术指标要求。上述分析过程为飞行模拟器的设计提供了一套有效的研究方法。
