摘要：

This paper shows how Bishop's receptance method can be used to derive the transmission of vibrational energy across a structural joint. The results are averaged over frequency bands and on the assumption of light damping an approximate formula for the coupling loss factor is obtained. This is an important parameter in the statistical energy analysis method of estimating the response of structures to broad-band random forces. The results compare well with those obtained by the travelling wave method.
