The fatigue durability test of automobiles includes driving tests on customers actually road,rough road tests on the proving ground,and indoor rough road simulation tests.Indoor rough road simulation testing has become one of the important measures of automotive development and verification due to its not affected by external factors,good repeatability,high accuracy,short testing time,and low cost.The most critical technology is the simulation of road load spectra in indoor rough road simulation test,this article mainly introduces the acquisition and editing of automotive road loads,TWR iteration technology,and analysis of iteration results.The test results indicate that the 4-poster tire coupled road simulation test bench can effectively simulate road loads,thereby achieving rapid fatigue testing of the entire vehicle and its components.
