新型大负载飞行模拟器六自由度运动系统是根据大型飞机飞行模拟器的特点,结合传统Stewart六自由度运动系统结构,提出的一种由气动单元提供支撑力、驱动单元提供驱动力的新型六自由度运动系统。它能在有效地提高运动系统承载能力的同时降低驱动单元的负载,使系统安全性得到了大幅度提高,为满足大型飞机飞行模拟器六自由运动系统要求提供了一条新的技术实现途径。在ADAMS平台上建立新型电动六自由度运动系统虚拟样机,结合飞行模拟器系统要求,通过对系统进行动态仿真、自由度分析、结构运动学和动力学分析。得到各驱动单元、气支撑单元以及各铰链在不同运动状态下的驱动力、行程范围、运动速度等特性曲线,为整个运动系统的设计与制造提供依据。
The new large-load flight simulator 6-DOF motion system is based on the characteristics of large aircraft flight simulator, combined with the structure of the traditional Stewart six-DOF motion system proposed by a pneumatic unit to provide support force, the drive unit to provide the driving force of the new six Degrees of freedom exercise system. It can effectively improve the carrying capacity of the sports system and reduce the load of the driving unit, thus greatly improving the system safety. This provides a new technical approach to meet the requirements of the six-flight system of the large aircraft flight simulator. Based on the ADAMS platform, a new type of six-DOF kinematic system virtual prototype is established. According to the requirements of the flight simulator system, the dynamic simulation, freedom analysis, structural kinematics and dynamics analysis of the system are carried out. The driving force, stroke range, moving speed and other characteristic curves of each driving unit, air supporting unit and each hinge under different movement states are obtained, which provides the basis for the design and manufacture of the whole moving system.
