The method of application of SEA in structural design process for reducing structure-borne noise in machinery. Part 1, General procedure
(Wydawnictwa AGH, 2009) Yamazaki, Toru; Kuroda, Katsuhiko
The paper focuses on the finding which parts of machinery should be modified in order to reduce the noise. The countermeasure is decided by being based on the theoretical formulation the statistical energy analysis (SEA). The proposed process is applied to determine the countermeasures to structure-borne noise in a commercial product (A4 laser printer). This study is the first report of a series to develop a process based on the SEA.

The method of application of SEA in structural design process for reducing structure-borne noise in machinery. Part 2, Structural optimization of subsystems
(Wydawnictwa AGH, 2009) Kuroda, Katsuhiko; Kuratani, Fumiyasu|Yamazaki, Toru
This paper presents the formulation of the structural optimization method on the basis of statistical energy analysis. A4 laser beam printer consisting of eight finite elastic steel plates is considered as an example, where the mass is taken as a constraint function. Consequently, taking one CLF as the objective function, an optimization of the thickness of the shell elements is performed showing the efficiency of the structural optimization method.
