Abstract
The noise of vehicles such as exhaust noise has become a important problem in modern society. Noise is uncomfortable for human beings and it is one of the seven typical pollution defined in the social law. The noise of frequencies less than 100Hz exerts bad influence to human body. A truss core panel proposed in this study is excellent in the interception, absorbing and radiation of noise. So, in this study the simulation on the interception performance of a truss core panel which has high strength, high rigidity and low cost is carried out.
