| 摘 要： | 为了研究流体作用力、离心力及重力等载荷对混砂车搅拌叶轮模态的影响,建立了混砂车搅拌系统的三维模型,分别对叶轮的静态模态和预应力模态进行了分析。结果表明:各载荷对混砂车叶轮模态固有频率影响不大,叶轮在两种工况下固有频率变化较小,最大变化率仅为0.61%;在流固耦合作用下叶轮振型的第2阶及第3阶振型最大值有所减小,其他各阶振型最大值无显著增大。

| Abstract: | In order to study the influence of the fluid force,centrifugal force and gravity on the blender truck mixing impeller, the 3-D models is established. The static modal and prestressed modal are analyzed. The results show that the various loads have a little impact on the natural frequencies of blender truck mixing impeller. The natural frequencies changes lightly in the two conditions,with the largest change rate of only 0.61%. The maximum value of the second and third order vibration mode decreases under the fluid-solid coupling,and the maximum value of other vibration modes show no significant increase. |
