For a colloidal particle in a harmonic potential driven by a periodic signal,we study its thermodynamic behavior and obtain the exact expressions of the effective temperature and dissipated work by solving the corresponding Langevin equation. The results show that due to the cooperative effect of the potential,the signal and the noise,the energy of the environment can be transferred to the colloidal particle through the stirring action of the periodic driving force,which makes the effective temperature of the system increase greatly. Under the condition of dynamical resonance,the dissipated work also reaches its maximum.
