研究了确定机床固定结合面的等效刚度系数和等效阻尼系数的新方法。采用迭代计算和动态测试相结合的方法，在多种不同结合面条件下进行了实验和计算，得到了大量的实用数据，并且建立了机床固定结合面的等效参数通用数据库。
The new method to determine the equivalent stiffness coefficient and the equivalent damping coefficient of the fixed joint of the machine tool was studied. The method of combining iterative calculation with dynamic testing is used to carry out experiments and calculations under a variety of different bonding conditions. A large number of practical data are obtained and a general database of equivalent parameters of the fixed joint surface of the machine tool is established.
