| Abstract: | The free vibration characteristics of stringed beam structure were analyzed systematically with subspace iteration method of software ANSYS.Through a large amount of analysis of the different parameters,such as rise-span ratio,sag-span ratio,number of struts,number of lateral string,prestress,oblique angle,etc,the influence of several parameters on the free vibration characteristics of stringed beam structure as well as the pattern of free vibration were obtained. |
