| Abstract: |
| 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. |
