  1. In this paper, dynamic stability of parametrically excited flexible cam - follower system on the weakly nonlinear condition is investigated by using the combination of both the method of multiple scales and the technique of fourier series expansion. the equations of approximate transition curves in the plane of the dimensionless frequency and excitation ( amplitude ) parameter that separate stable from unstable solution are derived

    隨后,本文採用多尺度法並結合fourier級數展開,分析了不同的凸輪從動件運動規律和不同的凸輪的升程、停程以及回程的時間分配規律下,無間隙的周期時變凸輪系統模型的穩定性,獲得了各種規律下的凸輪系統的穩定區間圖。
  2. Firstly, the multiple modes and dispersion nature of ultrasonic lamb wave are investigated in theory. furthermore, optimization of excitation signal is performed experimentally with the four parameters : the transport mode, the center frequency, the amplitude and the number of the wave ’ s peak value

    本文首先從理論上分析lamb波的多模式和頻散現象,在理論基礎上結合實驗在傳播模式、中心頻率、信號幅值、波峰數等幾個方面對lamb波進行優化。
