| 摘 要： | 瞬态动力分析是确定随时间变化载荷作用下的结构响应的技术分析,输入数据作为时间函数的载荷,输出数据是随时间变化的位移和其它导出量,如应力和应变 1].燃烧室外机匣是发动机承力和混合传力的重要部件,承受各种动态载荷,分析其瞬态振动位移及应力应变的变化很有必要.采用UG建模和ANSYS有限元分析相结合的方法对航空发动机燃烧室外机匣进行瞬态动力分析.结果显示,该方法是有效的.

| Abstract: | Transient Dynamical Analysis is used to obtain structure response under time-depended loads.The input data is used as time function loads and the output data is time-depended displacement and other derived variables,such as stress and strain.In aero-engine analysis,combustor outer casing is a load bearing and force transfer part working under dynamic loads.It's necessary to analyze the variation of it's transient vibration displacement,stress and strain.The author analyzed the transient dynamical response to combustor outer casing of an aero-engine based on UG modeling and ANSYS FEM analysis.The result shows that this method is effective. |
