| Popis: | 96 The purpose of this report is to study the process of using commercial software ANSYS in the modal analysis of a golf club. Through the computational modal analysis, the characteristic parameter of vibration can be obtained, including natural frequencies, the mode shapes of deformation and stress distribution. The chosen element type and discretization scheme were first verified by analyzing a thin-walled cantilevered rod. By way of comparing to modal characteristics between the golf club made of the composite material and steel, the reason of adopting the composite maternal instead of steel can be obviously demonstrated. It is found that the calculated natural frequencies converge very quickly by using the finite element model with increasing number of nodes. However, the computational time increased more or less linearly with the number of nodes employed in the model. The first few natural frequencies of the graphite/epoxy golf club by present ANSYS model were found to be within 10% of accuracy comparing with those by experimental modal analysis. |
