Conventional metal material has smaller damping and less energy consumption,therefore constructional elements which are made of these material will radiate strong noise due to the vibration force.It will solve the problem if use high molecular material or the damping property of metal material,because damping materials can reduce much more noise than the general materials in the same forces.C.L.
Luo[14] invented a kind of metal plastic composite materials including 45# steel and nylon 66.Experiments showed that its amplitude and natural frequency dropped and damping ratio increased in the same order modal.In his book,M.
