摘要
利用小波尺度函数多分辨率和逼近精度高的特点,将小波有限元应用于复合材料数值分析中,建立了复合材料抽油杆小波有限元模型,推导了复合材料抽油杆小波单元刚度方程,求解了复合材料抽油杆横向振动前八阶固有频率,并将分析结果与ANSYS模拟结果进行比较。结果表明:小波有限元在复合材料数值模拟方面具有较高的计算精度。
Making use of the character that wavelet scaling function has multi-resolution and accurateapproximation accuracy, we use wavelet finite element method in numerical analysis, and establishwavelet finite element model of compost malarial sucker rod. Then we derive the composite materialwavelet element stiffness equation and get the first eight natural frequency of the compost materialsucker rod. We compete the result with ANSYS simulation results. The result shows that wavelet fi-nite element has high calculation accuracy in numerical simulation of composite material.
