一、前言主传动系统是机床的重要组成部分,其正确合理的设计对提高机床各项性能有重要意义。但长期来采用经验类比法设计,盲目性很大,设计周期长且难于找到最佳方案,无法满足对机床提出的愈来愈高的要求。近年来优化设计为机床主传动系统的设计开拓了新途径。 I. Preface The main drive system is an important part of the machine tool, and its correct and reasonable design is of great significance to improve the performance of the machine tool. However, the long-term experience of analogy design, blindness, long design cycle and difficult to find the best solution, can not meet the higher and higher requirements of the machine. In recent years, the optimal design has opened up a new way for the design of the main drive system of the machine tool.
