摘要:悬臂梁作为发动机安装车上最重要的承力构件之一,除必须具有足够的强度和刚度之外,同时还要保证质量较轻,最终才能保证发动机安装车的正常使用和安全性。通过分析悬臂梁的工作原理,建立出零件的初步三维模型,通过设定边界条件和添加载荷,利用有限元数值模拟技术进行分析,结果显示强度满足要求、但质量过大,需进一步优化改进。利用Workbench环境中的拓扑优化模块对零件进行形状和尺寸的优化,最终得到了满足强度条件下质量更轻的悬臂梁。经实物称量,该零件的实际质量较设计之前减少了14.25 kg、减幅达51.59%,为今后该类型零件的设计提供一定的参考。

Abstract:As one of the most important bearing members on the engine installation car, the cantilever beam must have sufficient strength and rigidity, at the same time, which ensure the light weight, so that which finally ensure the normal use and safety of the engine installation car. By analyzing the working principle of the cantilever beam, a preliminary 3D model of the part is established. By setting the boundary conditions and adding the load, the finite element numerical simulation technology is used for the analysis, The results show that the strength meets the requirements, but the quality is too large, and further optimization and improvement are needed. In this paper, the shape and size of the part are optimized by the topology optimization module in the workbench environment, Finally, the cantilever beam with lighter weight is obtained under the condition of strength. After weighing in real thing, the actual quality of the part is reduced by 14.25 kg compared with the design. The reduction rate is 51.59%, which provides a certain reference for the design of such parts in future.
