Abstract :In motor vehicles, driveshafts, which enable the power produced in the engine to be transmitted to the differential, are one of the major elements in the drivetrain. A driveshaft compensates for the angular and axial distance differences between the elements in the drivetrain, depending on road conditions while it provides rotation and power transmission. A driveshaft prototypes of frozen designs are manufactured to validate the product by subjecting it to laboratory and vehicle tests respectively. Laboratory tests are conducted via testing machine specially developed for driveshafts. Durability test, which is one of the laboratory tests to be conducted to determine the durability performance of a drive shaft in terms of the number of safe cycles for driveshaft, takes a long time causing the high cost. In this paper, an approach to estimate the durability performance of a driveshaft, using a new-developed analytical model, is presented. A new model has been developed that gives the number of safe cycles for the driveshaft as an output. The number of safe cycles here refers to the number of driveshaft revolution without any failure on the propeller shaft. The results from the new-developed model were compared with the durability test results of the driveshafts, it was seen that the results approached the test results with a difference of less than 5%. When the results obtained from the test and the model are considered, it is suggested to use the new-developed model instead of the durability test in determining the durability performance of the driveshaft.
