Around the topic, the weak points of the traditional platform is analyzed first, such as complex arithmetic, long calculating time, high needs of hardware and so on. A real time control method based on virtual simulation is suggested to separate the complex positive/negative calculation of space kinematic and real time motion control. And a"3-2-1"type 6DOF platform is designed with the reference of the MAST (Multi-Axis Shaking Table) of MTS. The kinematic and dynamic calculation of the platform is finished. According to the calculating result, the control system of the"3-2-1"type 6DOF platform including 6 linear servo electric cylinders is designed and constructed. And the professional software Pro/E is used to do the 3D model and 6DOF motion simulation of the platform. The motion curves of the pistons of the 6 cylinders are exported with the simulation. At last the control software is programmed with Microsoft Visual Basic 6.0 and realizes the functions with the commands of GE series motion controllers. When loading the motion curves exported with the simulation, every cylinder can follow the curve very well and the platform realizes the hoped 6DOF motion.

围绕选题,本论文首先分析了传统的运动平台控制方法所存在的算法复杂、解算耗时长、硬件需求高的缺点,提出了一种基于虚拟仿真的实时控制方法,该方法将复杂的空间运动学正、反解与实时运动控制相分离;之后,参考MTS公司的MAST多轴振动平台,设计了新型的"3-2-1"型六自由度平台,并进行了运动学及动力学计算,根据相关计算结果,设计与搭建了包括驱动6个直线伺服电动缸在内的"3-2-1"型六自由度平台控制系统;接着,使用Pro/E对"3-2-1"型六自由度平台进行了三维建模和六自由度运动学仿真,并由仿真直接获得了6个直线伺服电动缸的活塞杆的相应运动曲线;最后使用Microsoft Visual Basic 6.0编写了控制软件界面,通过调用GE系列运动控制卡的各种命令函数实现了控制系统的相关功能,而当加载仿真得到的各缸运动曲线后,每缸均能很好地跟踪输入曲线,使平台实现了期望的多自由度运动。
