  The role of tensor force on the collision dynamics of $^{16}$O+$^{16}$O is
investigated in the framework of a fully three-dimensional time-dependent
Hartree-Fock theory. The calculations are performed with modern Skyrme energy
functional plus tensor terms. Particular attention is given on the analysis of
dissipation dynamics in heavy-ion collisions. The energy dissipation is found
to decrease as an initial bombarding energy increases in deep-inelastic
collisions for all the Skyrme parameter sets studied here because of the
competition between the collective motion and the single-particle degrees of
freedom.
  We reveal that the tensor forces may either enhance or reduce the energy
dissipation depending on the different parameter sets. The fusion cross section
without tensor force overestimates the experimental value by about 25\%, while
the calculation with tensor force T11 has good agreement with experimental
cross section.
