本文的目的主要為研究實驗模態分析(Experiment Modal Analysis)配合有限元素法(Finite Element Method)的模擬方法，對P-V-T-C測試機結構進行模型驗證包括模態振型(Mode Shape)與自然頻率(Frequency)的比對，模擬方面利用Pro/Engineer建立模型，轉入ANSYS軟體分析。另一方面為實驗分析，由衝擊鎚(Hammer)的激發與加速規(Accelerometer Sensor)的擷取資料使用LABVIEW做頻譜分析得到實驗振型與實驗自然頻率。最後兩者互相比對根據誤差修改ANSYS的參數達到設計最佳化的目標。
透過原理、實驗、模擬三大方向去做研究，並且成功開發本論文所需求的頻譜分析軟體，經過實驗結果，誤差值為可接受的範圍，但是距離複雜機械振動的分析仍有進步的空間，往後希望能夠推廣至機械振動的領域繼續研究。

In order to compare the Mode Shape and the Natural Frequency of the P-V-T-C testing machine, Experiment Modal Analysis and the Finite Element Method were applied to study the vibration behavior of the P-V-T-C tester. Using Pro/E CAD software to build the model and transform it into ANSYS mesh for simulation. Experiments were done by knocking the machine with a hammer and receiving the data from an Accelerometer Sensor. To analyze the experimental data, LABVIEW software was used. We could compare both simulation and experiment results with the data and refine the parameter in ANSYS to meet the design requirements.
Through theorem, experiment and simulation, spectrum analysis system in LABVIEW was successfully built. The error data of the spectrum system lied on an acceptable range for the P-V-T-C testing machine. This vibration analysis system was expected to be further developed and expanded and can be applied to other mechanical engineering systems.
