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...
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...
This paper presents the development of a simplified dynamic model for air-conditioning systems taken the energy, mass, and momentum balances between room air and surroundings into account. The newly developed dynamic simulation model is referred to as "Kamimura-Kurosu" (simply "KK") model in association with developer's name. In this paper, the objective is to illustrate the application...
