The experiment apparatus has been developed, which is based on software ( labview ) and hardware ( pci board ni 6024e ). the displacements and generative force at the tip of the ipmc actuators were measured with respect to the different voltages, frequents and various waveforms which include square, sinusoidal, and triangular wave
實驗選取了不同電壓幅值，不同頻率的方波、三角波、正弦波三種波形作為電激勵信號，利用高速攝像記錄ipmc的位移變形，並通過力傳感器實測了ipmc試樣末端的輸出力。Based on frequency - spectrum - transformation, this algorithm first changes acceleration spectrum into displacement spectrum, then calculates its amplitude, angular frequency and initial angle related to every displacement spectrum, finally sums up all the displacement components and forms the time course of the measured vibration
該方法採用頻譜轉換法，首先將加速度譜轉換成位移譜，再計算出位移譜中每個頻率分量對應的幅值、圓頻率和初相角，最後對各位移分量進行疊加得到振動位移的時間歷程。The results showed that the displacement of the surrounding rock of cavern evidently decreases with the increase of in - situ stress side pressure coefficient, as well as the decreasing rate of surrounding rock displacement of cavern with increasing at the condition of < 1 are significant larger than that of > 1 ; when < 1, the displacements of measured points in cavern increase then decrease with the increasing incident angle of shear wave, while, when > 1, the displacements decrease then increase with the increasing incident angle of shear wave, and the influence of incident angle on the displacements of measured points tends to decrease with the increasing in - situ stress side pressure coefficient
分析結果表明，地震荷載作用下，硐室位移隨地應力側壓系數的增加明顯減小，地應力側壓系數< 1時的硐室位移量值隨側壓系數的變化幅度明顯大於地應力側壓系數> 1時的情況；當側壓系數< 1 ，隨剪切波入射角的變化，硐室測量點位移響應先增加后減小；而當側壓系數> 1 ，隨剪切波入射角的增加，硐室測點位移先減小后增加，同時隨地應力側壓系數的增加有減小的趨勢。
