In this work, we study the stochastic resonance (SR) effect in a bistable optomechanical system (OMS) driven by a strong coupling field and two weak signals (an optical field and a mechanical force). The SR phenomena are observed at the cooperation of input signals and system noise. Except for the SR resonance peak, an additional intrawell resonance peak appears on the signal-to-noise ratio curve. When two signals co-act on our system, the interference effect between the optically induced SR and the mechanically induced SR can be generated. In particular, a unique beating effect, which makes the SR effect robust against the initial phase difference of two signals, appears in the SR synchronization process with unsynchronized signals.
