Feature based parametric modeling technique and application for the composite flywheel in dynamic design

运用基于特征的参数化建模技术建立了某复合材料飞轮实体模型,并采用ANSYS8.0软件对其进行模态分析,计算出该飞轮前十阶固有频率及转速。建模过程表明基于特征的参数化建模在复杂结构的动态分析中具有一定优越性,为该飞轮的形状优化设计和动力学仿真研究奠定了基础。

Used parametric modeling based on feature technique to build a composite flywheel's model, and modal analysis was done on it with ANSYS. The first ten natural frequencies and the corresponding rotate speed were obtained. This showed that parametric modeling based on feature technique has some advantage in the dynamic analysis of intricate structure, and also established the foundation of shape optimum design and dynamics simulation.
