Passing Ability Evaluation and Impact Factors Analysis of Articulated Vehicle with 6×4 Tractor

摘要

Passing Ability of articulated vehicles is tested and analyzed, which are combined of different 6×4 tractors and different loaded semitrailers. Test methods and test procedure is designed and developed. 90 times of test data are collected in '3rd Swap Trailer Transport Recommended Vehicles Test'. Articulated vehicles are combined of 25 different 6×4 tractors and 21 different loaded semitrailers. Test data are statistically analyzed and passing ability is evaluated according to the requirements of GB 1589-2004. Linear regression is used to study how tractor front overhang, distance between center of tractor fifth wheel and tractor first axle and semitrailer first wheel space impact passing ability. The results can serve as both advices in improving articulated vehicle and data references in developing and amending standards.
