- Abstract:
- Plastering machine is a new type of construction machinery which can replace manual operation to plaster internal wall. First the dynamic model of plastering board-mortar is analyzed and the D-P model of mortar is established by using LS-Dyna finite element analysis software in the page，and the accuracy of the model is verified through the experiment. The stress wave transmission and distribution of the mortar layer is analyzed in the process of vibration compaction. The impaction of plastering board’s vibration amplitude and frequency on the mortar surface is showed. The simulation results show that the stress of mortar increases with the increase of the vibration amplitude and increases first and then decreases with increasing frequency. The mortar surface settlement decreases with the increasing speed of plaster board. The results also show that there is a suitable resonance frequency range for a certain kind of mortar no matter how the process parameters are combined. It provides theoretical basis for the prediction of compaction effect and selection of compaction process parameters.
