本文论述了相似理论和量纲分析的原理和相似指标、相似准数的确定方法以及在机床结构设计和试验中的应用。它对合理制订系列产品的技术参数、使类比设计更加合理、减少试验工作量等有一定的现实意义。
This paper discusses the principle and similarity index of similarity theory and dimension analysis, the method of determining the similar standard and its application in the design and test of machine tool structure. It is reasonable to formulate a series of technical parameters of the product, the analogy design more reasonable and reduce the workload of the test has a certain practical significance.
