摘要：从边界条件和布置方向出发，充分利用V型机体的上部空间，设计支撑柱+支撑条、支架+平板和镂空支架（球铁）+镂空平板3个固定支架方案，基于拓扑优化思维，通过仿真，从模态、强度、疲劳和滑移4个方面详细评估系统可靠性；为消除设计冗余，更换轻量化的材料得到镂空支架（铸铝）+镂空平板方案。结合游艇用途、系统结构和使用工况特点，根据经验评估，选用可靠性系数更高的镂空支架（球铁）+镂空平板方案进行产品开发，镂空支架（铸铝）+镂空平板方案作为技术储备，用于其他振动和冲击小的细分市场。

Abstract:In order to get the optimal design, three intercooler supporting structures, column+strip, support plate and hollow support plate, are designed for a Vtype diesel, and the assembly and maintainability are analyzed. Topological optimization method is used to simulate and evaluate system reliability in terms of modality, strength, fatigue and slip. Based on lightweight design, hollow support plate (aluminum) is designed to get lighter weight and better performance.Considering the layout and using conditions of yacht, hollow support plate (cast iron) with higher safety factor is determined. The aluminum design is used for technical reserve, which can be used in other applications with slight vibration and shock.
Keywords:intercooler; bracket; topological optimization; lightweight; modal analysis; strength analysis; fatigue analysis; slip analysis
