HYBRID MOUNT FOR SHIPS

摘要

A hybrid mount for ships is provided to have an effect to reduce vibration and noise generated from machinery by reinforcing an active piezoelectric device on an elastic rubber. A hybrid mount for ships includes a center plate(1), an elastic rubber(2), a supporting plate(3), a piezoelectric device(4), a vibration detector(5), and a controller(6). The center plate is supported vertically on a ground. The elastic rubber is adhered on the center plate and absorbs vibration and impact. The supporting plate is located on the elastic rubber for transmitting the vibration and the impact of machinery to the elastic rubber. The piezoelectric device is formed inside the elastic rubber and provides force by being expanded and contracted. The vibration detector detects the vibration of the supporting plate and outputs an electrical signal. The controller controls a drive of the piezoelectric device by outputting the electrical signal.
