This paper prepare a kind of epoxy constrained damping material,And studied the modulus,damping layer,constrained layer of different material selection for the damping properties of system,obtained when the damping layer modulus is small,the damping layer thickness is small,the damping effect is improved,and choice different constrained layer damping material is also have some effect for the structure.
