摘要
本文根据弯曲波理论和声强测量原理提出了结构振动能量分布和传输特性的新技术方法.理论分析、实验室研究和实际应用结果表明,用振动强度来分析结构振动问题可得到振动能量的流向和分布,测量技术简单且易于掌握,具有可接受的实际应用精度.
Based on the principles of sound intensity measurement and theories of solid wave produced by the bending vibration, a new method of the measurment on the distribution and transmission of vibrational energy in engineering structures is presented in this paper. The results of theoretical analysis and some experiments done in laboratory and tracked vehicles show that the technique proposed in this paper is simple, feasible and has acceptable accuracy in practical engineering problems.
