摘要:

伺服系统机械刚度的好坏不仅是影响其抵抗外部干扰能力的重要因素之一，同时也对整个系统的控制性能起着决定性的作用。提出了一种伺服系统机械刚度的计算方法，以电动舵机为例，详细推导了组成系统各传动机构的机械刚度与整个系统机械刚度的数学关系，指明了在研究伺服系统刚度时忽略前级传动机构刚度的两个前提条件。

Abstract:

The mechanical stiffness of the servo system is good or bad is not only affecting one of the important factors for its resistance to external interference ability, also plays a decisive role in the control performance of the entire system The method of calculation of the mechanical stiffness of a servo system is put forward, electric steering gear, for example The mechanical relationship between the mechanical stiffness of the transmission mechanism at all levels of an integral system with the mechanical stiffness of the entire system is deduced in detail, and it pointed out two prerequisites to ignore the mechanical stiffness of the before- transmission in the study of the stiffness of the servo system.
