| 中文摘要: |
| 目的 通过对整车强化腐蚀试验及其结果进行梳理，归纳出一种适合用于评价整车防腐性能的评价方法。方法 对整车强化腐蚀试验中出现的问题点及其产生的原因进行分析，挑选出对问题点贡献度较大的因素作为评价维度，并通过加权计算得出扣分总和，以此归纳出一种整车强化腐蚀试验问题的评价方法。结果 整车强化腐蚀试验中，腐蚀问题的表观腐蚀程度（L）、腐蚀问题的出现时间（T）、问题部位/属性分类（P）以及质量系数（N）是对腐蚀问题贡献度较大的4个因素，用该4个因素对应评级的评分值乘以对应权重系数并求和，即可得出整车腐蚀问题评价扣分值（LTPN法）。结论 运用该评价方法可对整车强化腐蚀试验后各整车之间防腐性能进行横向比较，可对单个整车各部位之间进行横向评价，可对底盘等部位进行划分区域评价，可对整车强化腐蚀试验问题点进行风险排序。 |
| 英文摘要: |
| The work aims to generalize an evaluating method applicable to corrosion resistance of full vehicle by summarizing full vehicle accelerated corrosion test and its results. Four evaluating dimensions were established based on top 4 factors contributing to full vehicle corrosion resistance. Top 4 factors mentioned above were figured out as follow: appearance corrosion level (L), occurrence time of corrosion (T), failure position/property classification (P) and quality coefficient (N). Deducted points of corrosion issues could be acquired by summation with scoring value of each factor multiplied by corresponding weighting coefficient (LTPN method). This evaluation method can be used for horizontal comparison of corrosion resistance among vehicles after full vehicle accelerated corrosion test, horizontal comparison among all components of a single full vehicle, zoning evaluation of such components as chassis and risk prioritizing of problem spots in the test. |
