以压装江淮轿车5T18型号变速箱中的中间轴、输入轴、输出轴上相应轴承的轴系压装机中的液压缸为研究对象,分析了引起液压缸共振的原因及激振信号源的频率,并通过ANSYS建立该液压缸模型,划分网格,进行模态分析,得出其三阶固定频率的变形图和相应的节点位移云图;通过观察图形得出相应的三阶固定频率以及各阶固定频率状态下对液压缸的影响,比较是否与激振信号源的频率相重合,并提供了解决的方法,从而有效地避免了因共振带来的压装偏差,确保了轴承的精确压装,为该系列压装机关于避免共振问题提供了参考.

Based on being connected in Jianghuai auto 5 t18 type gearbox intermediate shaft, the input shaft and out-put shaft of the corresponding bearing shaft installed in the hydraulic cylinder pressure as the research object, the pa-per analyzes the cause of hydraulic cylinder resonance and the frequency of the excitation signal source. So, the hy-draulic cylinder model is established by ANSYS, and division of grid and modal analysis are carried out. It is con-cluded that the deformation figure of third order fixed frequency and the corresponding node displacement nepho-gram, by observing the graph of the third-order fixed frequency and the fixed frequency condition influence on hy-draulic cylinder. Comparing with the frequency of the excitation signal source, it provides the solution so as to effec-tively avoid the installation due to resonance deviation and ensure the precision of bearing pressure equipment and avoid resonance problem for this series of presses.
