Globular clusters are supposed to be the possible places that intermediate-mass black holes (IMBHs) may reside. The existence of the IMBHs may influence the properties of the clusters. Direct n-body simulations are employed to model the equilibrium states of globular clusters with IMBHs. We study the dynamical interactions between the central IMBH and the globular cluster. These dynamical signals could be valuable hints for the existence of IMBHs and thus lead to future techniques of IMBH detections.
