| description | The invention discloses a method and a device for testing a loss factor of a damping material of a tractor cab, and the method comprises the steps: clamping one end of a metal strip pasted with the damping material on a measurement support, and transmitting an excitation signal to the free end of the metal strip through a vibration exciter in a non-contact manner; the vibration meter measures a vibration response signal of the clamping end of the metal strip in a non-contact mode, and the signal processing unit obtains an excitation signal of the clamping end of the metal strip and the vibration response signal of the free end of the metal strip and carries out data storage and processing so as to obtain the loss factor of the damping material. The testing device and the testing method in the scheme are simple, rapid, accurate and economical, and can be used for optimizing the design and the performance of damping materials of various applications.
