Using the adaptive time-dependent density matrix renormalization groupmethod, we numerically investigate the expansion dynamics of bosons in aone-dimensional hard-core boson model with three-body interactions. It is foundthat the bosons expand ballistically with weak interaction, which are obtainedby local density and the radius $R_n$. It is shown that the expansion velocity$V$, obtained from $R_n=Vt$, is dependent on the number of bosons. As aprominent result, the expansion velocity decreases with the enhancement ofthree-body interaction. We further study the dynamics of the system, whichquenches from the ground state with two-thirds filling, the results indicatethe expansion is also ballistic in the gapless phase regime. It could help usdetect the phase transition in the system.
