摘要
目的为了保证在不同试验场转场试验结果的一致性,整理出一套合理的转场验证流程。方法对整车强化腐蚀试验需要用到的特殊道路、设备进行考察,再通过对比不同试验场试验车辆的结果,通过层层验证并对最终结果进行加权计算,得出最终的结果一致性。结果首先验证道路及设备的基本参数,然后对整车腐蚀试验结果的腐蚀深度(D)及划线扩蚀量(L)一致性进行验证,所有基本参数都通过后,最终对整车所有零部件主观评价得分(G)进行对比。得分对比的结果结合市场反馈的质量问题配比进行加权计算,最终得出两试验场试验一致性的数值86.2%(R)。结论利用该方法可以全方位地将试验场之间进行对比,科学地判定试验场是否满足整车强化腐蚀试验的转场要求。
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.
