611 油圧脈動の温度変化に関する一考察(GS5,9,12 流体工学・設計,研究討論セッション)

抄録

It is known that industrial machinery emits hydraulic noise, and that the noise can change under operational conditions. Noise can play a role as a signal that indicates normal operation. It is therefore important to understand the behavior of the hydraulic pressure ripples that are a source of hydraulic noise under operation. This study has investigated the behavior resulting from temperature change. The variables controlling hydraulic pressure ripples have been defined, and the temperature characteristics of those variables have been obtained. A cause-analysis on the behavior has been conducted using calculations including the temperature characteristics. They have been verified experimentally.
