文中提出将自适应神经网络技术用于以压电陶瓷为执行元件的车内噪声主动控制研究中,通过以控制车身板件振动来降低结构的声辐射,进而实现车内噪声主动控制的技术路线,并进行了车身板件的振动主动控制试验和车内噪声的主动控制试验,取得了较好的减振降噪效果,为今后类似研究提供了参考。
In this paper, adaptive neural network technology is applied to the research of active noise control in the vehicle with piezoelectric ceramic as the actuator. The technology of active noise control in the vehicle is realized by controlling the vibration of the body plate to reduce the sound radiation of the structure , And carried out the active control test of vehicle body panel vibration and the active noise control in the vehicle, and achieved good vibration and noise reduction effect, which provided reference for similar research in the future.
