| 中文摘要 | 本文主要利用數值方法來模擬提動閥系統的運作,並觀察控制型提動閥在供給壓 力小於崩潰壓力時所產生的混沌振盪。在此考慮管長與閥室體積的變化對系統混沌振盪之 影響。我們利用相平面與能量頻譜來識別系統的狀況,並使用龐加萊圖觀察其奇異吸子的 形狀,對於系統整體的週期變化則以分歧圖檢視。 |
| 英文摘要 | The instability and chaotic vibrations that occur in a pilot-type poppet valve circuit operated below the cracking pressure are studied numerically. The system consists of a poppet valve, an upstream plenum chamber, a supply pipeline, and an orifice inserted between the plenum and the pipeline. The numerical simulations of the system at different under-operated pressures were carried out for the variations of pipeline length and the plenum volume. The simulation results are analyzed with various dynamical forms containing the phase diagram, power spectrum, and Poincare map. Moreover, the instability is investigated in detail by invoking the bifurcation diagram. |
