Document Type and Number:
Japanese Patent JP2015160212
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a spinning analyzer and a spinning analysis method capable of obtaining a highly accurate analysis result in short analysis time.SOLUTION: The present invention concerns a spinning analyzer and a spinning analysis method. A spinning analyzer according to one aspect includes: a natural vibration analysis unit (42) calculating a natural vibration mode on the basis of an analysis model; a mesh creation unit (44) creating FEM analysis meshes in the analysis model; an analysis condition setting unit (46) setting an analysis condition; an attenuation model addition unit (48) adding an attenuation model to each mesh; and an analysis unit (50) performing an analysis by solving an equation of motion for each mesh to which the attenuation model is added.
