Fatigue Design of Alloy Materials Part Used Vehicle Base on Ride Simulation Test
A dynamic model of drive and ride systems is established based on the technology of virtual prototype and the dynamic load spectrums on the different work sections of a final drive shaft are obtained through a simulation riding test. The distribution of random loads is analyzed, two dimension joint probability density function under multiple working conditions is acquired using the method of weight coefficient, and then a fatigue design spectrum in the full-life distance of the drive shaft could be achieved. According to the materials P-S-N curve and two dimension probability Miner rule, the fatigue lives of the parts are calculated, thus its section size d/D and the spline round angle can be designed based on all these means. As a result the designed drive shaft is 25 percent lighter than the former shaft on the condition of satisfying the service life.
