中文摘要 | 本論文研究週期激振下的負載螺栓接頭,其運動方程式是二自由度質量彈簧及阻尼 系統,其穩定解是由特徵方程式根來決定,由衰退時間指數函數,指數函數和時間sine(或 cosine)函數乘積,和收歛交錯級數和時間sine(或cosine)函數等組合而成,其連接平盤 在頻率定義域內的力傳遞比與位移傳遞比,我們證明當時間趨近無限時此二傳遞比均能以交 錯收歛級數表示,其最佳值是發生在開始振動不久某時間內,同時於連接平盤的力傳遞比與 位移傳遞比的近似值的估計誤差亦能決定。 |
英文摘要 | The present investigation studies the preloaded bolted joint subjected to periodic excitation. The equations of motion are derived as a two-degree-of-freedom spring-mass- damper system. The steady state solutions are the combinations of the decaying exponential function of time, the multiplication of decaying exponential functions and sine (or cosine) functions of time and the multiplication of the convergent alternating series and sine functions of time which depends on the roots of the characteristic equation. The force and motion transmissibility ratios between joint plates are obtained in the frequency domain. we show that the force and motion transmissibility ratios are expressed in the form of alternation convergent infinite series when time approaches infinite. The optimum value will occur at some time after starting. The error estimates of the approximated values of the force and motion transmissibility ratios between joint plates are also determined. |
