摘　　要：以C型弹簧管为研究对象,建立了有限元分析模型,并利用ANSYS灵敏度分析技术对影响弹簧管固有频率的主要结构参数进行了研究,得出了弹簧管固有频率和其主要结构参数之间的关系,研究表明:弹簧管的一阶固有频率对自由端有效位移影响最大,增大弹簧管的短半轴和壁厚的尺寸能提高一阶固有频率,增大弹簧管的圆直径和曲率半径能降低一阶固有频率.该研究结果可为弹簧管的减振设计和进一步的动力学分析提供了理论依据.C-type spring tube is the object of study in this thesis and build finite element analysis modal.Make use of sensitivity analysis technology of ANSYS to study the main structure parameter which affects spring tube inherent frequency.Get the relation between spring tube inherent frequency and its structure parameter.Study shows that：The 1 spring tube natural frequencies of the free end displacement of the most effective,increasing the spring tube and the wall thickness of the short half-shaft size can improve the first-order natural frequency,increasing the diameter of the spring tube and the radius of curvature to reduce first-order natural frequency.It provides the theory basis for vibration reduction design and dynamics analysis of spring tube.
