本文提出了一种螺栓联接机床结构静力特性的计算方法，以改进现有的CAD技术。在迄今为止开发的方法中，除了巴克博士的方法外，没有考虑螺栓连接的存在。在N.Back博士提出的计算方法中，接头刚度的经验表达式已被使用，而在本方法中，理论接头刚度矩阵已被用于考虑螺栓接头的交叉接收。采用有限元方法计算了螺栓连接的界面压力和位移分布，并根据计算机结果研究了螺栓连接的一些静态性能。为了阐明所提出的方法的适当性，螺栓连接开始分离时的理论临界施加载荷与实验值进行了比较。
In this paper, one computing method for static behavious of a machine tool structure having a bolted joint has been proposed to improve the present CAD technique. In the methods developed so far, except that of Dr. Back's, the existence of a bolted joint is not taken into consideration. the empirical expression of the joint stiffness has been used in the computing method presented by Dr. N.Back, whereas in this proposed method the theoretical joint stiffness matrix has been employed to consider the cross receptance of a bolted joint. The interface pressure and displacement distribution of the bolted joint were computed by means of the finite element method, and then from computer results some static behaviours of a bolted joint have also been investigated. To clarify the propriety of the proposed method, the theoretical critical applied load at which the bolted joint begins the separation, was compared with the experimental value.
