摘要
建立了某燃气轮机发电机组公共底座精细模型,通过有限元计算,对模型进行了优化设计,通过对公共底座自由状态及实际安装状态下的振动模态分析,获得了各阶模态参数,进而验证了发电机组公共底座设计刚度及结构的合理性。
A detailed model of the common fixing pedestal of gas turbine generator set was established.By means of finite element analysis,the optimization design of the model is accomplished.In the course,vibration modal analysis of common fixing pedestal in free and fixing state was carried out,and the modal parameters were obtained.Therefore,the design stiffness and structural rationality of the common fixing pedestal of gas turbine generator is verified.
