为了使用一个驱动器，即可实现输出平台的纯中心转动，则输出平台的对角位置
为了使用一个驱动器，即可实现输出平台的纯中心转动，则输出平台的对角位置需要同时获得大小相等方向相反，不在同一直线上的作用力。分析Scott-Russell机构时，其输出端可获得一对作用力，这对作用力作为杠杆机构的输入力。利用杠杆机构的对称性，可以得到如图四a所示的结构示意图。巧妙的利用了杠杆的对称性，使用一个驱动器即可实现纯中心转动，并使结构紧凑。图四b展示了输出平台旋转中心的有限元仿真结果，输出平台受到力矩的作用时，其旋转中心落在输出平台的中心，输出平台可做纯中心转动，因此对微动平台进行建模和分析时，只需要对其一半进行分析即可。

In order to use a single driver to realize the pure center rotation of the output platform, the diagonal position of the output platform needs to be equal in magnitude and opposite in direction but not on the same straight line. When analyzing the Scott-Russell mechanism, a pair of forces can be obtained at its output end, which is used as the input force of the lever mechanism. Using the symmetry of the lever mechanism, a schematic diagram of the structure shown in Figure 4a can be obtained. Ingenious use of the symmetry of the lever, a pure center rotation can be achieved with a single driver, and the structure is compact. Figure 4b shows the finite element simulation results of the rotation center of the output platform. When the output platform is under the action of torque, its rotation center falls on the center of the output platform. The output platform can do pure center rotation, so the micro-motion platform is modeled and When analyzing, only half of it needs to be analyzed.

In order to use a single driver, the pure center rotation of the output platform can be achieved, the verse position of the output platform needs to be at the same time obtained in the opposite direction of equal size, not in the same straight line. When analyzing the Scott-Russell mechanism, a pair of forces can be obtained at the output, which act as input forces for the leveraged mechanism. Using the symmetry of the leveraged body, a diagram of the structure shown in Figure 4a can be obtained. Clever use of the symmetry of the lever, the use of a single drive for pure center rotation, and compact structure. Figure 4b shows the limited meta-simulation results of the rotation center of the output platform, when the output platform is affected by the torque, the center of its rotation falls in the center of the output platform, the output platform can do pure center rotation, so the micro-dynamic platform modeling and analysis, only need to analyze half of it.

In order to use one driver to realize the pure center rotation of the output platform, the diagonal position of the output platform needs to obtain the force of equal magnitude, opposite direction and not on the same line at the same time. When the Scott Russell mechanism is analyzed, a pair of forces can be obtained at its output end, which are used as the input forces of the lever mechanism. Using the symmetry of the lever mechanism, we can get the structure diagram as shown in FIG. 4A. Ingenious use of the symmetry of the lever, using a driver can achieve pure center rotation, and make the structure compact. Figure 4B shows the finite element simulation results of the rotation center of the output platform. When the output platform is under the action of torque, its rotation center falls in the center of the output platform, and the output platform can rotate purely. Therefore, when modeling and analyzing the micro motion platform, only one half of it needs to be analyzed.<br>
