The Lambda binding energies of hypernuclei ranging from light to heavy masses are investigated systematically in the framework of the Skyrme-Hartree-Fock (SHF) approach. Calculations are performed with the combinations of the NN interactions SLy4 and SkI4 and various interactions, including the Skyrme-type forces and the microscopic forces. It is demonstrated that the Skyrme-type SLL4 and YMR forces can well describe the experimental data overall better compared to other Skyrme-type forces, while the microscopic interaction results deviate a bit from the experimental data. In addition, the shrinkage effects caused by hyperon on the deformation indeed exist for the deformed light nuclei, while not for the heavy nuclei regardless of the interactions.
