| Abstract: | Reducing the vibration of the automobile cavity is one of the effective ways to eliminate automobile interior noise. This paper set up a simplified automobile interior noise active control system with vibration exciter, actuator and controller as the main components, and the system simplify the automobile cavity model for plate to weaken vibration plate as the goal, then achieve automobile interior noise active control. Using simple harmonic sine and cosine signal as incentives from the vibrator, which is used for simulateing initial vibration of plate. Controller by using fuzzy control algorithm directly controls the vibration of the piezoelectric ceramic actuators, the vibration of the piezoelectric ceramic actuators is used for eliminating the vibration of the plate, accordingly, completed the simulation of the automobile interior noise active control system. Simulation results show that the automobile interior noise active control system adopted in this paper made automobile cavity vibration reduced by 23%, to solve the problem of the automobile interior noise caused by automobile engine and powertrain vibration provides an effective method. |
