Durability Analysis and Evaluation of a Frame type Heavy Truck Cab

Abstract:

According to loading spectrum collected in the road test, the bench test was designed. Fatigue life simulation and test of a frame type heavy truck cab were conducted, and the results were compared with those of the benchmark. The results of simulation and test were comparable, and the design weaknesses were checked out. Finally, a new method was proposed that force decreasing rate was regarded as an indicator to evaluate cab’s equivalent life.
