Fluid-structure coupling construction models of a tile-adhesive-concrete system were developed based on the coupled Eulerian-Lagrangian method(CEL method).The pattern of adhesive application,rows of adhesive application and type of tile leveling loads of a robot were simulated,and their influence law and mechanism on the indices of installation quality including tile resilience value,contact areas and defect distribution were investigated.The results show that the adhesive with horizontal application possesses smaller plastic deformation,keeps stable shape of strips and distributes at equal spacing,compared with the one with vertical application.Increasing rows of mortar extrusion has little effects on the tile resilience value and contact areas,but leads to an obviously narrower defect of tile-adhesive interface with a more uniform distribution.Compared with a single compression load,its coupling with vertical vibration causes inhomogeneous plastic deformation and hence decreases the resilience value of tile and the tile-adhesive contact area.In contrast,the coupling of shear vibration with compression is beneficial to the reduction of tile resilience value and remarkably increases the tile-adhesive contact area,and reduces the interfacial defect effectively.
