本文研究了电-气混合定位系统的动态特性。该系统由气动、电动和机械驱动子系统组成。气动驱动系统控制惯性质量块承受的压力，即压力与作用在惯性质量块上的重力相对应;小容量的电动驱动系统通过滚珠丝杠作为机械驱动子系统，实现惯性质量块的垂直移动。为了开发电-气混合定位系统，本文通过计算数据与实验结果的对比，特别是通过精确测量滚珠丝杠的摩擦力，对该系统的数学模型进行了修正。通过数值计算，研究了电动驱动系统通过滚珠丝杠使惯性质量块垂直上下运动一个周期时的功耗和动态特性。在一个周期内的功耗数据将有助于在设计阶段选择合适的驱动电机。
This paper deals with the dynamic characteristics of an electro-pneumatic hybrid positioning system. This system is composed of a pneumatic, an electric and a mechanical driving sub-system. The pneumatic driving system controls the pressure supporting the inertial mass, which means that the pressure is correspondent to the gravitational force acting on it. And the electric driving system with small capacity moves the inertial mass vertically through a ball screw as a mechanical driving sub-system. In the present study, in order to developing the electro-pneumatic hybrid positioning system, the mathematical model of this system has been refined by comparing calculation data with the experimental results, especially by measuring precisely frictional force of the ball screw. And the power consumption as well as the dynamic characteristics has been investigated numerically when the inertial mass is moved vertically upwards and downwards during one cycle by the electric driving system through the ball screw. The data on the power consumption during one cycle will be useful to select a suitable driving motor at the design stage.
