Purpose: The transfer cases for special trucks must have reliability criteria because military vehicles with high off-road and cross-country ratios must perform various missions accurately in harsh environments. In this paper, reliability criteria for special truck transfer cases are presented and the reliability of transfer cases is evaluated based on them.
Methods: The performance, safety, and environmental evaluation criteria were prepared based on the field use conditions of the special trucks and accelerated life test method was designed using load conditions and life time of the transfer cases.
Results: Several kinds of test equipments and evaluation criteria were designed and manufactured for reliability test of transfer cases. As a result of tests using them, it was verified that the transfer cases satisfied the evaluation criteria of the performance tests and the accelerated life test.
Conclusion: The transfer cases are guaranteed the B10 life of 12,000km at a 90% confidence level because no failure was found in the product after accelerated life testing of two samples.
