摘要
研究了机械台体对转台频响特性的影响。首先要求出机械台体的固有频率,基于模态分析理论,建立了转台有限元模型,得出前五阶振型的固有频率和振型,论证了转台机械台体设计将直接影响频响指标。
The influence of the mechanical platform resonant frequency on the reponse margin of the servo control system is studied. Based on the modal analysis theory, we establish the finite element modal of the mechanical platform with the natural frequency to get the first 5-order models and frequencies. It indicators the design of the mechannicl system may directly have some effects on the frequency indexes of the servo system.
