一、机械环节的特性磁盘伺服定位系统性能的提高往往受机械环节的限制,在设计、研制和生产过程中,机械环节应作为系统的一个主要环节来加以重视并进行改进。因此定位机构的动力特性的测试和研究显得尤为重要。 1.机械环节特性的描述一个机械构件(或系统)受一个(或一组)输入量(力)的作用,它将发生运动。这运动要用一组 First, the mechanical aspects of the characteristics of Disk servo positioning system performance is often limited by the mechanical aspects, in the design, development and production process, the mechanical aspects should be as a major part of the system to be valued and improved. Therefore, the dynamic characteristics of the positioning mechanism of the test and study is particularly important. 1. Description of Mechanical Characteristics A mechanical component (or system) is subjected to a (or a set of) inputs (forces) that will move. This exercise to use a group
