压水堆核电厂用全自动多螺栓四同步安装机的结构创新研究

首先在结构上创造了新型螺栓、螺母和一套崭新的安装机。在主机上去掉了精密、复杂、昂贵的机器人或机械手，改用结构简单的集成齿轮机构，以实现同步旋拧功能；运用现代流体传动与控制的理论，建立流本控制的数学模型和传递函数，从而实现了4个同步安装的效果。

Innovation on Structure of All Automatic Multi-Studs Four Synchronous Installing Machine Used in PWR

In this paper,first of all from structure bring forth many new ideas.New stud,nut and a brand-new installing machine have been designed.In main machine,the integrated gear mecha-nism simple in structure achieves synchronous turning function,instead of the precision,complicated,expensive manipulator or robot.In aspect of supervising and controlling,computer electro-hydraulic proportional control and advanced examine measure system have been designed to measure stress and extension of stud as tensioning.Mathematics model and transmit function have been built using theory of modern times fluid transmission and control.As a result four synchronous installin g has been achieved.
