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.

Key words: blender truck, fluid-solid coupling, modal analysis, natural frequency, impeller, prestressed modal
