摘要
以重庆轨道集团委托川东船厂制造的单轨道岔梁为例,利用有限元分析软件Hyper Works对道岔梁的结构进行了静强度分析。静强度分析的结果表明,梁体强度完全满足使用要求,但材料存大较大的浪费。在保证承载力及必要安全裕度的前提下,利用Hyper Works软件中的Opti Struct模块对道岔梁进行了拓扑优化和进一步的尺寸优化。优化后,梁体质量降低了18.4%,优化效果明显。
Taking the monorail turnout beam made by the Eastern Chongqing Shipbuilding Industry as an example,the static strength of the beam turnout structure is analyzed by using finit element softw are Hyper Works. The results show that the beam intensity could fully meet the requirements of bearing capacity,but there is relatively large waste of materials. So the Opti Struct module in Hyper Works is used to make topology optimization and size optimization in the premise that the bearing capacity and the necessary safety margin of the beam are ensured. After the optimization,the beam weight is decreased by18. 4% with very obvious effect.
