运用有限元方法对1G-175A旋耕机的主要部件之一的侧边齿轮箱体进行了静态和动态的强度与刚度计算,并对其动特性用结构模态试验方法进行了分析,验证了所建立的有限元模型的合理性。
The finite element method was used to calculate the static and dynamic strength and stiffness of the side gearboxes, one of the main components of 1G-175A rotors. The dynamic characteristics of the 1G-175A rotors were analyzed by the modal structural modal analysis. The rationality of the established finite element model.
