摘要
针对复杂系统力学模型难以准确建立和分析的问题,以某型电磁高频疲劳试验机作为工程背景,建立其力学模型并进行合理的适当简化,通过分析系统主要的大刚度部件对系统力学特性的影响,确定了该型主机刚度部件的设计原则,为此类主机的设计提供科学的力学分析理论依据。
For the modeling and analysis problem in the complex system dynamics model,this paper modeled and simplified the dynamic model of a certain type of electromagnetic high frequency fatigue testing machine.By studying effects of the main components on the mechanical properties,the design principle is determined for the main components,a scientific theoretical method is provided to the design of this type machine.
