The Solutions and Study on Lifting and Falling Noise for Car Door Glass
Based on the theory of equivalent radiated power of panel, the performance of equivalent radiated power of the door pan- el under the unbalanced centrifugal force excitation of the elevator motor is calculated and analyzed. It is confirmed that the inner door panel is the key factor to produce vibration and noise. Under the constraints on the project cost and time node, the vibration and noise ra- diation of the door inner panel can be significantly reduced by optimizing the motor vibration transfer path, the optimization scheme has been verified by physical test and subjective quality evaluation, and it has been implemented in this car.
