全息干涉计量法的发展,为机床静刚度、动刚度及热刚度的研究提供了一种极有潜力的新的分析工具。本文推导了用全息照相测量机床法向位移和振幅的简捷计算法,其特点是光路简单、计算迅速,并且计算结果同其它仪表的测量结果一致。因此,根据全息照相计算位移十分麻烦这一缺点得到了克服。本文还分析了影响动刚度模拟试验精度的因素,并指出了进行试验的正确原则。 The development of holographic interferometry provides a very new analytical tool for studying the static stiffness, dynamic stiffness and thermal stiffness of the machine tool. In this paper, a simple calculation method for the normal displacement and amplitude of a holographic measuring machine tool is deduced. Its characteristic is that the optical path is simple and the calculation is rapid, and the calculation result is consistent with the measurement results of other instruments. Therefore, the disadvantage of calculating the displacement based on the hologram is very troublesome. This paper also analyzes the factors affecting the accuracy of the dynamic stiffness simulation test, and points out the correct principles for conducting the test.
