摘要
将定端的园锥型编织网壳及支承简化为连续锥壳一板组合结构,分别建立具有各向同性、正交各向异性和各向异性体材质的定端结构的参数化动态仿真模型,根据实际结构的试验模态参数,运用结构动力学优化方法, 在ANSYS平台上进行了仿真研究,获得了较为精确的定端实际结构的动态仿真模型。对定端支承板系统进行了动态优化设计,获得了较为满意的结果。
The end basket with a form of double layered conical weave net is simplified into a model of continuous conical shell-plate combined structure. Stator end structures with isotropic, orthotropic and anisotropic materials are modelled as parametric dynamic simulation model separately. In accordance with the test results of experimental modal analysis, dynamic optimization method is used to perform simulation research on the ANSYS platform. The dynamic simulation model of stator end structure is obtained, and it has the same dynamic characteristics as stator end structure. The dynamic optimisation design of supporting plates system is performed, and ideal results are achieved.
