【摘要】 利用ANSYS软件中的子空间迭代法,分析了张弦梁结构的自振特性,针对不同的参数如矢跨比、垂跨比、撑杆数、横索数、预应力度和整体倾角等进行了大量参数分析,得出了各参数对张弦梁结构的自振特性的影响及张梁弦结构的自振规律.更多还原

【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.更多还原
