摘要
基于Kane方法建立起六面体柔性桁架多体结构动力学数学模型,得到了数值仿真计算结果。同时对所给模型用ANSYS软件进行了有限元分析运算,并将两种结果和实验分析进行了比较。比较结果显示所建立动力学模型正确,可为空间柔性桁架振动控制研究提供依据。
Based on Kane methods a dynamic mathematical model of hexahedron flexible multi-body truss is established and simulated numerically. And by using software ANSYS a FEA (Finite Element Analysis) is processed for the given model. Then both results are compared with that achieved through numerical calculation and experimental analysis. The comparison shows that the dynamic mathematical model of hexahedron flexible multi-body truss is correct and can provide basis for the vibration control investigation of spatial flexible multi-body truss.
