The elastic element of the original design with an electrically controllable damping material was created.
The pressure wave alternately passes through the liquid layer in the process chamber, the receiving bottom-membrane 4 of the sensor, the gasket from the vibration damping material 5, the gasket from the dielectric material with high electrical strength 6, the current collector 7, the piezoelectric cell 8, the copper waveguide 9.
The viscoelastic damping material was introduced to the brake disc manufacturing and installation in the automotive industry, which has a good effect on the brake squeal problem.
Transfer matrix method is used to calculate the high order modes and the moving wave characteristics of the shell, and it was observed that high order vibration characteristics of rotating thin shells and hard coating damping material had a more obvious effect on the natural frequency at the high vibration order.
The engine bay heat shield has been filled with acoustic damping material to reduce powertrain noise and diesel cars are equipped with extra acoustic seals to further reduce noise intrusion.
