中文摘要: |
针对矩形大开孔的拱形平板封头处结构复杂,常规计算方法难以进行应力分析的问题,课题组提出使用ANSYS软件进行模拟计算,并采取MPC接触方式使T型加强筋与其它部件相连接,得到该结构应力分布规律。在满足强度要求与疲劳性能的基础上,使用ANSYS优化模块对结构进行优化设计。分析结果表明:平板封头矩形大开孔结构在优化后质量减少19.6 %,实现了轻量化的目标,有效降低了生产制造成本。 |
英文摘要: |
In view of the complicated structure of arch sectioned flat head with large rectangular opening ,it is difficult to analyze the stress with the convention rules. The method of simulating in ANSYS was put forward in this paper, the MPC contact method was adopted to connect the T stiffener with other parts to obtain the distribution rules of stress. The analysis of the flat head was conducted by the optimization module of ANSYS under the requirements of strength and fatigue resistance. The analysis results show that the weight of flat head decreases by 19.6% after optimization, achieve the goal of lightweight and reduce the manufacturing cost remarkably. |
