介绍了胶原纤维及胶原类纤维材料的结构特点,即具有特殊的结构和优良的粘弹性,具有微孔和共振吸音的双重特点。通过对胶原纤维吸音减振作用机理的研究,推导并建立其吸音减振数学模型,并对胶原纤维作为吸音材料的应用做了进一步展望,为该类材料在声学方面的实际应用奠定了理论基础。
The structural characteristics of collagen fibers and collagen fibers are introduced. They have the special structure and excellent viscoelasticity. They have the dual characteristics of micropores and resonance sound absorption. By studying the mechanism of acoustical absorption and vibration damping of collagen fiber, the mathematical model of its absorption and damping is derived and established. The application of collagen fiber as sound-absorbing material is further prospected, which provides a theoretical basis for the acoustical application of this kind of material .
