Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。

When the large rotating arm rotates, the transmission gear is driven to rotate around the fixed gear to rotate the planetary gear, which drives in turn the small rotating arm to rotate in the direction opposite to the large rotating arm, so that the shaft of the small rotating arm reciprocates across the rotation center of the large rotating arm.

当大旋臂旋转时，传动齿轮受到驱动沿固定齿轮周转并带动卫星齿轮转动，卫星齿轮带动小旋臂作与大旋臂反向的旋转，从而使小旋臂上的固定轴随着大、小旋臂的旋转不断往复越过大旋臂的旋心作直线运动。

The analysis results indicate that the vibration fractional factor with rotating frequency has a close relationship with both rotating speed of rotor and damping of bearing under constant acceleration. When rotating acceleration is small and damping is large, the transient response is not sensitive to the variation of rotating speed; otherwise the imbalance response with constant acceleration and the response in stable state will build up obvious differences near critical rotating speed.

研究结果表明：在恒加速条件下，转子同频振动分量与转子的转速、支承阻尼等因素密切相关，当角加速度较小且阻尼较大时，其瞬态响应对转速的波动不敏感；而当角加速度较大或阻尼较小时，恒加速过程不平衡响应与稳态响应在临界转速附近将产生明显的差异。

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。
