| description | When working, the geometric distribution shape of concrete in concrete mixing
truck's rotary drum changes continuously, which cause a great difficulty for
studying the dynamic performance of the mixing drum. In this paper, the
mixing system of a certain type of concrete mixing truck is studied. A
mathematical formulation has been derived through the force analysis to
calculate the supporting force. The calculation method of the concrete
distribution shape in the rotary drum is developed. A new transfer matrix is
built with considering the concrete geometric distribution shape. The effects
of rotating speed, inclination angle and concrete liquid level on the
vibration performance of the mixing drum are studied with a specific example.
Results show that with the increase of rotating speed, the vibration
amplitude of the mixing drum decreases. The peak amplitude gradually moves to
the right with the inclination angle increasing. The amplitude value of the
peak's left side decreases when tilt angle increases, while the right side
increases. The maximum unbalanced response amplitude of the drum increases
with the decrease of concrete liquid level height, and the vibration peak
moves to the left. |
