To address the height flushness between the long glass fiber-reinforced composite tailgate and side panel after high-temperature exposure, this study combines real-vehicle solar exposure tests, oven aging tests, and finite element analysis. Results indicate that the material creep is the primary cause of the long-term cumulative deformation of the tailgate under high-temperature conditions. Both the optimization of inner-panel reinforcing ribs and the extension of the reinforcement plate can effectively disperse local stresses and suppress creep deformation. A feasibility analysis identifies the reinforcement plate extension as the optimal solution, as it corrects flushness without requiring mold modifications, while offering low cost and rapid implementation. These findings provide valuable insights for the design of similar polymer tailgates.

为解决长玻纤增强聚丙烯复合材料汽车行李箱盖高温服役后与侧围面差超差的工程问题,结合实车暴晒试验、恒温烘烤试验与有限元仿真分析,开展行李箱盖高温变形规律研究与结构优化方案对比。结果表明,材料蠕变特性是行李箱盖高温长期累积变形的核心诱因;内板加强筋优化与加强板延伸优化均可有效分散局部应力、抑制蠕变变形。经工程可行性分析,采用加强板优化方案,可在不改动内板模具的前提下满足面差精度要求,兼具开发成本低、落地周期短的优势,可为同类塑料行李箱盖结构优化提供参考。

为解决长玻纤增强聚丙烯复合材料汽车行李箱盖高温服役后与侧围面差超差的工程问题,结合实车暴晒试验、恒温烘烤试验与有限元仿真分析,开展行李箱盖高温变形规律研究与结构优化方案对比。结果表明,材料蠕变特性是行李箱盖高温长期累积变形的核心诱因;内板加强筋优化与加强板延伸优化均可有效分散局部应力、抑制蠕变变形。经工程可行性分析,采用加强板优化方案,可在不改动内板模具的前提下满足面差精度要求,兼具开发成本低、落地周期短的优势,可为同类塑料行李箱盖结构优化提供参考。

To address the height flushness between the long glass fiber-reinforced composite tailgate and side panel after high-temperature exposure, this study combines real-vehicle solar exposure tests, oven aging tests, and finite element analysis. Results indicate that the material creep is the primary cause of the long-term cumulative deformation of the tailgate under high-temperature conditions. Both the optimization of inner-panel reinforcing ribs and the extension of the reinforcement plate can effectively disperse local stresses and suppress creep deformation. A feasibility analysis identifies the reinforcement plate extension as the optimal solution, as it corrects flushness without requiring mold modifications, while offering low cost and rapid implementation. These findings provide valuable insights for the design of similar polymer tailgates.
