| Abstract: |
| Objective To sort out a series of reasonable verification process before transferring test grounds to ensure the consistency of the test results in different grounds. Methods Roads, equipment and facilities to be used for intensified vehicle corrosion test were investigated and the results of vehicles in different test grounds were compared. Finally, the consistency of the final results was obtained by means of multi-layer verification and weighted calculation. Results Firstly, basic parameters of road and equipment were verified. Then the consistency of corrosion depth (D) and scribe lines (L) was verified. After all the basic parameters passed the verification, the subjective evaluation grades of all parts of the whole vehicle were compared. The result of grades comparison was weighted by the proportion of quality problems given by market feedback. Finally, the consistent values (G) 86.2% of the two test sites were obtained. Conclusion This method can be used to comprehensively compare the test fields and scientifically determine whether the test field meets the requirements on test ground transferring of the vehicle corrosion test. |
