SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING POWER SYSTEM ANALOGIES层流范围,领域 Hydraulic systems within the laminar flow regime at least function in ways, which are quite analogous to mechanical and electrical systems. Later in these discussions the equations of analogy will be developed. At this point, illustrations show the K analogies between systems. Fig. II shows the analogies relating 解 p hydraulic parameters to those of electrical systems and Zly translatory and rotary mechanical systems. Similar analogies I could be developed for pneumatic, thermal or other energy systems. These elements can be combined in ways which at least in electrical systems are termed"passive"networks. They are passive because no energy is added to the system in the networks though energy is lost through conversion to heat in the resistance elements. These networks affect the stability of transmission systems at various frequencies when subjected to periodic oscillation such as sinusoidal cyclingSCIENCE AND TECHNOLOGY ENGLISH FOR MECHANICAL ENGINEERING POWER SYSTEM ANALOGIES Hydraulic systems within the laminar flow regime at least function in ways, which are quite analogous to mechanical and electrical systems.
